Subject: [PATCH] rtlwifi: rtl8821ae: remove set but not used variable 'type' in translate_rx_signal_stuff

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

drivers/net/wireless/realtek/rtlwifi/rtl8821ae/trx.c: In function 'translate_rx_signal_stuff':
drivers/net/wireless/realtek/rtlwifi/rtl8821ae/trx.c:309:6: warning:
 variable 'type' set but not used [-Wunused-but-set-variable]

It never used since commit 21e4b0726dc6 ("rtlwifi: rtl8821ae: Move driver from
staging to regular tree")
