mac802154: use atomic ops for sequence incrementation
This patch will use atomic operations for sequence number incrementation while MAC header generation. Upper layers like af_802154 or 6LoWPAN could call this function in a parallel context while generating 802.15.4 MAC header before queuing into wpan interfaces transmit queue.
