Subject: [PATCH] staging: qlge: replace msleep with usleep_range

qlge_close uses msleep for 1ms, in which case (1 - 20ms) it is preferable
to use usleep_range in non-atomic contexts, as documented in
Documentation/timers/timers-howto.rst. A range of 1 - 1.05ms is
specified here, in case the device takes slightly longer than 1ms to recover from
reset.
