drm/amdgpu: fix userq hang detection and reset
Fix lock inversions pointed out by Prike and Sunil. The hang detection
timeout *CAN'T* grab locks under which we wait for fences, especially
not the userq_mutex lock.
Then instead of this completely broken handling with the
hang_detect_fence just cancel the work when fences are processed and
re-start if necessary.
