ath9k: Fix issues in the main btcoex timer
* ath9k_mci_update_rssi() is required only for cards that use MCI scheme. Make sure that it is not called for 3-wire cards. * Call ath9k_ps_wakeup() early since register accesses are made in ath9k_mci_update_rssi(). * Fix usage of btcoex_lock to handle no_stomp_timer.
