Subject: [patch 075/123] b43/b43legacy: Wake queues in wireless_core_start

2.6.33-stable review patch.  If anyone has any objections, please let me know.

-----------------

From: Larry Finger <Larry.Finger@...inger.net>

commit 0866b03c7d7dee8a34ffa527ecda426c0f405518 upstream.

If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.

In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.
