[PATCH] staging: rtl8723bs: replace msleep() with fsleep() in rtw_cmd.c

["Jose A. Perez de Azpillaga" <azpijr@gmail.com>]

Replace msleep() with fsleep() in rtw_cmd.c to improve delay
precision and follow modern kernel practices.

Specifically, this fixes a checkpatch warning for the 10ms delay
in _rtw_free_evt_priv() and updates the 100ms polling loop in
rtw_chk_hi_queue_hdl() for consistency.
