[PATCH] staging: r8188eu: fix array_size.cocci warning

From: Guo Zhengkui
Date: Tue Nov 16 2021 - 01:42:00 EST


Fix following array_size.cocci warning:
./drivers/staging/r8188eu/core/rtw_rf.c:38:48-49: WARNING: Use ARRAY_SIZE.

ARRAY_SIZE() defined in <linux/kernel.h> is safer because it uses
__must_be_array().
