[PATCH] staging: qlge: change msleep to usleep_range

[Tobias Alam]

This patch changes msleep() to usleep_range() based on
Documentation/timers/timers-howto.txt. It suggests using usleep_range()
for small msec(1ms - 20ms) because msleep() will often sleep longer than
the desired value. Issue found by checkpatch.
