drm/amdkfd: mark queues as reset after a full GPU reset

Browse source

During a GPU reset, evict_process_queues_cpsch() calls remove_queue_mes()
per queue, which fails with -EIO because the recovery path already holds
the reset domain write lock. The loop aborts on the first queue, leaving
the rest with is_active still set while the reset wipes the MES queue
table.

When the process later exits, process_termination_cpsch() sends
REMOVE_QUEUE for doorbells MES no longer knows about. MES rejects them,
the driver reports it as a timeout and concludes MES is unrecoverable,
so it requests another GPU reset.

  Failed to evict queue 2
  GPU reset(1) succeeded!
  failed to remove queue from MES, doorbell=0x1002
  MES might be in unrecoverable state, issue a GPU reset

Mark every queue as reset in kgd2kfd_post_reset(). This clears is_active,
corrects the queue counts and sets is_reset so the queue is skipped later.

Add a verbose argument to set_queue_as_reset() so the full reset path
does not log a message for every queue.
