[PATCH] mac80211: hoist sta->lock from reorder release timer

The patch "mac80211: AMPDU rx reorder timeout timer" clashes
with "mac80211: use netif_receive_skb in ieee80211_rx callpath"

The timer itself is part of the station's private struct and
it gets killed whenever the station is removed. Therefore
the extra sta->lock protection (that can interferes with the
tx path) is not necessary.
