On full reset, mci reset will put LNA update on 2G mode. And
Whenever 2g5g_switch is forced at the end of full reset, lna
update should not be skipped. Whenever 2g5g switch is enforced,
WLAN need not to wait for the completion of MCI messages. Not
doing so, is affecting WLAN rx and causing beacon loss when
BTCOEX is enabled on AR9462.
