drm/amdgpu: Drop vm_manager PASID to VM mapping

VM lookup users now resolve DRM PASIDs through the global PASID xarray:

	PASID -> fpriv -> VM

The per-device vm_manager.pasids xarray is no longer needed.

Remove PASID registration and removal from the VM init/fini paths, drop
vm_manager PASID initialization/cleanup, and remove the xarray from
struct amdgpu_vm_manager.

The PASID is allocated only after amdgpu_vm_init() completes, so the
initializer no longer consumes or assigns a PASID. Remove the now-unused
argument while keeping vm->pasid as per-VM state for TLB flushes and
other hardware programming paths.

v6:
- Remove the now-unused PASID argument from amdgpu_vm_init().
- Remove the related vm->pasid assignment and error-path reset from VM
  init.
- Keep vm->pasid in struct amdgpu_vm for existing hardware users.
