[PATCH 3/3] staging: rtl8723bs: use usleep_range() instead of msleep(10)

[Raushan Kumar]

msleep() can sleep for up to 20ms for requested durations under
20ms, due to jiffies timer granularity, as noted in the kernel's
own delay.h documentation. Replace msleep(10) with usleep_range()
in chk_bmc_sleepq_hdl() for more accurate short-duration sleeps,
as flagged by checkpatch.pl.
