mac802154: rework sdata state change to running
This patch reworks the handling for setting the state like mac80211. We use bit's instead a bool variable. The mutex is not needed because it use test and set bits which are atomic operations. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
