gpu: nvgpu: fix NVGPU_COND_WAIT_INTERRUPTIBLE
When called with timeout=0, NVGPU_COND_WAIT_INTERRUPTIBLE macro
ignores the return code from wait_event_interruptible. As a result
we do not detect when the call is interrupted, and the calling
process hangs.
Use wait_event_interruptible return code in case of infinite timeout.
