[PATCH] staging: rtl8723bs: replace msleep with usleep_range for short delays

[Sridhar Arra <sridhar.arra.dev@gmail.com>]

The checkpatch.pl tool warns that msleep() for values less than 20ms
can be inaccurate. This patch converts the 10ms msleep to
usleep_range(10000, 11000) to provide more precise timing using
high-resolution timers.
