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().
