e1000e: convert short duration msleep() to usleep_range()

With durations less than 20ms, the jiffies or legacy timer backed msleep()
may sleep ~20ms which might not be what the caller expects.  Instead, it
is recommended to use the hrtimers backed usleep_range().  For more, see
Documentation/timers/timers-howto.txt.  Issues reported by checkpatch.

In addition, remove unnecessary sleep in e1000e_write_nvm_spi().
