drm/amdgpu/userq: make sure queue is valid in the hang_detect_work
Thread 1: Running amdgpu_userq_destroy which eventually remove
the queue from door bell and set userq_mgr = NULL.
Thread2: An interrupt might have scheduled the hang_detect_work
which still need userq_mgr to be valid but could get an NULL
ptrs.
To fix that make sure we cancel the hang_detect_work again before
setting userq_mgr to NULL.
Along with that we also need all the queue va to remain valid till
we could be running anything on the queue and hence moving the
userq_va post hang_detect handler is cancelled.
