From: Colin Ian King <[email protected]>
The function rtw89_mac_enable_bb_rf is a void return type, so there is
no return error code to ret, so the following check for an error in ret
is redundant dead code and can be removed.
Addresses-Coverity: ("Logically dead code")
Fixes: e3ec7017f6a2 ("rtw89: add Realtek 802.11ax driver")
