drm/amdgpu: Serialize non TDR gpu recovery with TDRs

Browse source

Use reset domain wq also for non TDR gpu recovery trigers
such as sysfs and RAS. We must serialize all possible
GPU recoveries to gurantee no concurrency there.
For TDR call the original recovery function directly since
it's already executed from within the wq. For others just
use a wrapper to qeueue work and wait on it to finish.

v2: Rename to amdgpu_recover_work_struct
