issues:
gpu_recover() is re-entered by the mailbox interrupt
handler mxgpu_nv.c
fix:
we need to bypass the gpu_recover() invoke in mailbox
interrupt as long as the timeout is not infinite (thus the TDR
will be triggered automatically after time out, no need to invoke
gpu_recover() through mailbox interrupt.
