[patch 28/50] softmac: Fixed handling of deassociation from AP

[Chris Wright]

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

From: Ulrich Kunitz <kune@xxxxxxxxxxxxxx>

In 2.6.19 a deauthentication from the AP doesn't start a
reassociation by the softmac code. It appears that
mac->associnfo.associating must be set and the
ieee80211softmac_assoc_work function must be scheduled. This patch
fixes that.
