ath9k: Initialize MCI state correctly



The MCI configuration values are assigned
in ath9k_hw_btcoex_init_mci() which are used
by the MCI reset routine. When initializing
BTCOEX/MCI, ath_mci_setup() ends up using
uninitialized data. Fix this by setting up
the configuration parameters before issuing
a MCI reset.
