[PATCH][next] rtw89: Remove redundant check of ret after call to rtw89_mac_enable_bb_rf

[PATCH][next] rtw89: Remove redundant check of ret after call to rtw89_mac_enable_bb_rf

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

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")
