wifi: ath9k: Don't mark channelmap stack variable read-only in ath9k_mci_update_wlan_channels() 

This partially reverts commit e161d4b60a.

Turns out the channelmap variable is not actually read-only, it's modified
through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function,
so making it read-only causes page faults when that code is hit.
