mac80211: use just spin_lock() in ieee80211_get_tkip_p2k()
commit 655914ab863bcc06c84270e4159fd59002d6b529 upstream.
ieee80211_get_tkip_p2k() may be called with interrupts
disabled, so spin_unlock_bh() isn't safe and leads to
warnings. Since it's always called with BHs disabled
already, just use spin_lock().
