[patch 08/17] ath9k: fix oops on trying to hold the wrong spinlock

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Luis R. Rodriguez <lrodriguez@xxxxxxxxxxx>

commit a477e4e6d48d3ac7c7a75bad40585cb391e5c237 upstream

We were trying to hold the wrong spinlock due to a typo
on IEEE80211_BAR_CTL_TID_S's definition. We use this to
compute the tid number and then hold this this tid number's
spinlock.
