drm/amdgpu: Fix two reset triggered in a row
Some times a hang GPU causes multiple reset sources to schedule resets.
The second source will be able to trigger an unnecessary reset if they
schedule after we call amdgpu_device_stop_pending_resets.
Move amdgpu_device_stop_pending_resets to after the reset is done. Since
at this point the GPU is supposedly in a good state, any reset scheduled
after this point would be a legitimate reset.
Remove unnecessary and incorrect checks for amdgpu_in_reset that was
kinda serving this purpose.
