[PATCH] staging: rtl8723bs: fix msleep warning in core

[Ruziev Miraly <miraly.dev@gmail.com>]

The function description of msleep() states that msleep < 20ms can sleep
for up to 20ms. In LPS_RF_ON_check(), replacing msleep(1) with
usleep_range(1000, 2000) allows for more precise polling of the hardware
state without forcing the kernel thread to sleep for excessive periods.
