wifi: rtw88: remove CPT execution branch never used

[ Upstream commit 77c977327dfaa9ae2e154964cdb89ceb5c7b7cf1 ]

In 'rtw_coex_action_bt_a2dp_pan', 'wl_cpt_test' and 'bt_cpt_test' are
hardcoded to false, so corresponding 'table_case' and 'tdma_case'
assignments are never met.
Also 'rtw_coex_set_rf_para(rtwdev, chip->wl_rf_para_rx[1])' is never
executed. Assuming that CPT was never fully implemented, remove
lookalike leftovers. Compile tested only.

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