[PATCH] wifi: rtw88: coex: remove rf4ce unused code

[Dmitry Kandybka <d.kandybka@xxxxxxxxx>]

In 'rtw_coex_run_coex', 'rf4ce_en' is hardcoded to false,
so 'rtw_coex_action_rf4ce(rtwdev)' is never executed.
Assuming that rf4ce was never fully implemented,
remove lookalike leftovers. Compile tested only.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: a9359faaa47d ("rtw88: coex: add the mechanism for RF4CE")
