[PATCH v4 3/5] drm/amdgpu: use drm_file_err to add process info

[Sunil Khatri]

add process and pid information in the userqueue error
logging to make it more useful in resolving the error
by logs. drm_file_err logs pid and process name by
default.

Sample log:
[   42.444297] [drm:amdgpu_userqueue_wait_for_signal [amdgpu]] *ERROR* Timed out waiting for fence f=000000001c74d978 for comm:Xwayland pid:3427
[   42.444669] [drm:amdgpu_userqueue_suspend [amdgpu]] *ERROR* Not suspending userqueue, timeout waiting for comm:Xwayland pid:3427
[   42.824729] [drm:amdgpu_userqueue_wait_for_signal [amdgpu]] *ERROR* Timed out waiting for fence f=0000000074407d3e for comm:systemd-logind pid:1058
[   42.825082] [drm:amdgpu_userqueue_suspend [amdgpu]] *ERROR* Not suspending userqueue, timeout waiting for comm:systemd-logind pid:1058
