[PATCH 3/3] staging: rtl8723bs: use usleep_range instead of msleep for short delays

[Serhat Kumral <serhatkumral1@gmail.com>]

Replace msleep(10) and msleep(1) with usleep_range(10000, 20000) and
usleep_range(1000, 2000) respectively in os_intfs.c, because msleep is
imprecise and discouraged for short delays under 20ms.
This fixes the checkpatch.pl warnings:
WARNING: msleep < 20ms can sleep for up to 20ms; see function description of msleep().
