When a debug BO command completes, job->drv_cmd may already have been
freed. Accessing it from aie2_sched_drvcmd_resp_handler() can result in
a use-after-free and memory corruption.
Fix this by introducing reference counting for drv_cmd objects and
transferring ownership to the job while it is in flight. This ensures
that the command remains valid until the completion handler finishes
processing it.

When force_iova mode is enabled, amdxdna_remove() frees xdna->domain. If
amdxdna_gem_obj_free() is called after device removal, it may attempt to
access xdna->domain, resulting in a use-after-free.
Fix the race by adding freeing xdna->domain as a managed release action,
so its lifetime is managed by DRM and remains valid until all managed
resources are released.

amdxdna_remove() destroys notifier_wq. If amdxdna_gem_obj_free() is
called after device removal, it may attempt to flush notifier_wq,
resulting in a use-after-free.
Fix the race by allocating notifier_wq with
drmm_alloc_ordered_workqueue(), so its lifetime is managed by DRM and
remains valid until all managed resources are released.

In amdxdna_remove(), all amdxdna_client structures are freed after
calling drm_dev_unplug(). However, drm_dev_unplug() does not force
existing file descriptors to be closed, so amdxdna_drm_close() may be
called after amdxdna_remove() has completed.
As a result, accessing client->pid for debug output in
amdxdna_drm_close() can lead to a use-after-free, since the access is
not protected by drm_dev_enter().
Fix this by decoupling hardware teardown from client cleanup.
amdxdna_remove() only performs hardware-related cleanup, while
per-client resources are released from amdxdna_drm_close() when the
corresponding file is closed.

amdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's
drm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls
amdxdna_hwctx_sync_debug_bo(), but passes abo->client.
amdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle
namespace for debug_bo_hdl and as the owner of the hardware context xarray.
Those must match the file that supplied args->handle. The BO's stored
client pointer is object state, not the ioctl context.
Pass filp->driver_priv instead, matching the original handle lookup.

A command queue is considered valid and usable by the driver only when
it has a doorbell ID assigned (db_id != 0), meaning both the FW cmdq
creation and doorbell registration completed successfully.
However, when either ivpu_register_db() or set_context_sched_properties()
fails after ivpu_hws_cmdq_init() has already created the cmdq in FW,
the command queue is left registered in FW while the driver treats it as
uninitialized (db_id remains 0). On the next submission attempt the
driver tries to register the same cmdq again, which fails because FW
already has an entry for it.
Fix by calling ivpu_jsm_hws_destroy_cmdq() on error paths to properly
unwind FW state and allow subsequent registration attempts to succeed.
