Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_tkip_encrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:660:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]
drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_tkip_decrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:768:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]
drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_aes_encrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:1528:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]

It is not used since commit 554c0a3abf ("staging:
Add rtl8723bs sdio wifi driver")
