e1000e: cleanup USLEEP_RANGE checkpatch checks

Resolve strict checkpatch USLEEP_RANGE checks by converting delays and
sleeps as described in ./Documentation/timers/timers-howto.txt.  Three
other violations of the text have also been fixed.

CHECK:USLEEP_RANGE: usleep_range is preferred over udelay; see
Documentation/timers/timers-howto.txt
