Jesse Zhang 395e142b43 drm/amdgpu/userq: add reset helper and identify guilty user queue
If we get an interrupt for a bad user queue (bad opcode, etc.), add
a helper to handle the reset for user queues.

v2: squash in fixes
v3:
 - schedule the reset via amdgpu_userq_start_hang_detect_work() instead
   of open-coding mod_delayed_work()
 - drop the per-queue guilty flag; always reset the queue the hang
   detect work belongs to, matching the non-compute reset path
