wifi: rtw89: Fix TX fail with A2DP after scanning
[ Upstream commit f16c40acd31901ad0ba2554b60e0e2b0c7b59cde ]
There might be some racing between BT and WiFi after scan. Since
one of the TX related register will be modified by both FW and
rtw89_set_channel() in driver, which could cause Tx fail. Reorder
the calling sequence to only notify coexistence mechanism after
rtw89_set_channel() is called, so that there are no concurrent
operations.
