It is not really DMA specific, and moving it makes it possible to make some
functions in mac.c static

Use ieee80211_tx_status_ext instead of ieee80211_free_skb and
ieee80211_tx_status. This makes it compatible with 802.3 encap offload
and improves performance by removing a redundant sta lookup

ieee80211_tx_status_ext to immediately pass the rate to mac80211 after
receiving it from the firmware.
