Subject: [PATCH v4 06/15] staging: rtl8723au: else is not generally useful after a return

Correct a checkpatch.pl warning regarding rtl8723au's
rtw_security.c::crc32_init pointing out that having an else statement
after a break or a return is not useful.

drivers/staging/rtl8723au/core/rtw_security.c:105:
	WARNING: else is not generally useful after a break or return
