drm/amdgpu: recover user queues in the shared priv-fault helper

Browse source

If a priv/bad-op fault does not match a kernel queue slot, it belongs to a
MES-scheduled user queue. Extend the shared amdgpu_gfx_handle_priv_fault()
helper introduced by commit d8ab7636160e ("drm/amd/amdgpu: remove
duplicated code in gfx_v11 and gfx_v12") to recover it: gate on
adev->gfx.disable_uq, reset a compute user queue directly from its
doorbell, and for a gfx user queue (whose IV carries no doorbell) record
the HW slot and schedule the per-IP recovery worker.

v2:
 - gate on adev->gfx.disable_uq instead of !adev->enable_mes (Alex)
 - document why both the doorbell (compute) and HW-slot (gfx) reset
   paths are needed (Alex)

v3:
 - rebase amd-staging-drm-next. adapt to the
   commit 9243cf4777 ("drm/amd/amdgpu: remove duplicated code in gfx_v11 and gfx_v12");
   no functional change
