gpu: nvgpu: reset pm status on runtime_resume fail
If an error occurs during an attempt to perform a runtime_resume,
the runtime power management framework sets an error flag that
prevents further attempts to resume until the error is cleared.
nvgpu currently does not clear the flag, which causes nvgpu to
lock up if an error occurs during runtime_resume.
This change explicitly sets the device pm status to suspended
on error, which clears the error flag so that subsequent attempts
to resume will not be blocked.
