staging: rtl8723bs: remove unused cnt from recv_func()

The 'cnt' is used to show how many pending frames are processed, and the
debug code has been removed, so removing 'cnt' is safe.

Otherwise, clang warns:

core/rtw_recv.c:2030:7: warning:
	 variable 'cnt' set but not used [-Wunused-but-set-variable]
 2030 |                 int cnt = 0;
      |                     ^
