Subject: wl12xx: configure channel/band while FW is off
X-Git-Tag: v3.0-rc1~377^2~161^2^2~142^2~13

wl12xx: configure channel/band while FW is off

Initialize the channel and band from mac80211 conf even when the FW is
not yet loaded. This mitigates a bug in AP-mode where the channel was
never changed from its initial setting after FW boot and was therefore
never configured to FW.
