gpu: nvgpu: avoid false job timeout message

Browse Source 
The nvgpu timer API prints a message when the timer expires, but
expiration of that does not necessarily mean here that the job has
actually timed out, which is tested by comparing gp_get. Change the
expiration check to just peek instead of the default which prints to
log on expiration.
