Subject: [PATCH 2/3] staging: qlge: replace msleep with usleep_range

From: Drake Talley <drake@...ketalley.com>

Since msleep may delay for up to 20ms, usleep_range is recommended for
short durations in the docs linked in the below warning.  I set the
range to 1000-2000 based on looking at other usages of usleep_range.

Reported by checkpatch:

WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.rst
