Multiplying 1000000000 by four overruns a 'long' variable, as clang

expires = ktime_get_mono_fast_ns() + NSEC_PER_SEC * 4L;

Make this a 'long long' constant instead.

I'm not sure the ktime_get_mono_fast_ns() call is necessary here
either. Is it intentional because ktime_get_ns() doesn't work
during a driver suspend, or just a mistake?
