[PATCH] staging: rtl8723bs: replace msleep with usleep_range

[Marcos Andrade]

The msleep() function is not recommended for delays under 20ms
as it may sleep for longer than desired. Replace msleep(10) with
usleep_range(10000, 11000) to ensure a more precise delay and
better kernel scheduling behavior.
This resolves a checkpatch.pl warning.
