mac80211: choose first enabled channel for monitor
[ Upstream commit 041c881a ] Even if the first channel from sband channel list is invalid or disabled mac80211 ends up choosing it as the default channel for monitor interfaces, making them not usable. Fix this by assigning the first available valid or enabled channel instead.
