Christian raised a concern in V1 that the change introduces a much higher chance 
of aborting a GPU reset due to collision
[Dennis] In V1 patch, try_lock also will fail when other threads hold adev->lock_reset, which is a bug. Therefore I changed to use atomic_cmpxchg in V2 to fix this issue. If GPU is doing recovery, it make sense to reject the new recovery request.
