Subject: [PATCH] staging: rtl8723bs: replace msleep with usleep_range

checkpatch.pl says that msleep < 20ms can sleep for longer than expected.
The documentation says we should "Use uslee_range*()
whenever accuracy of *sleep() is not sufficient)

Replaced msleep(10) with usleep_range(10000, 11000) so the delay
is more accurate and percise
