staging: rtl8723bs: remove unused 'poll_cnt' from rtw_set_rpwm()

Browse Source 
The 'poll_cnt' is used to assist in polling hardware state. Current code
uses jiffies to determine timeout, so removing this value is safe.

Otherwise, clang warns:

core/rtw_pwrctrl.c:288:6: warning:
	 variable 'poll_cnt' set but not used [-Wunused-but-set-variable]
  288 |                 u8 poll_cnt = 0;
      |                    ^
