PCI/PM: Don't sleep at all when d3_delay or d3cold_delay is zero
msleep() still sleeps 1 jiffy even when told to sleep for zero
milliseconds. That can end up being 1-2 milliseconds or more. In the
cases of d3_delay and d3cold_delay, that unnecessarily increases suspend
and/or resume latencies.
Do not sleep at all for the respective cases if d3_delay is zero or
d3cold_delay is zero.
