drm/amdgpu: track faulted gfx user-queue slots

A gfx priv/bad-op fault IV carries only the HW slot (ring_id), not the
faulting user queue's doorbell. Add userq_priv_fault_slots (an atomic
bitmap of faulted slots, so concurrent faults are not dropped) and
userq_priv_fault_work to struct amdgpu_gfx; a worker drains the bitmap
and reads the doorbell back from each HQD to locate and reset the queue.
