[RFC PATCH 2/3] mac80211: disassociate when moving to new BSS

[Tomas Winkler <tomas.winkler@intel.com>]

This patch cleans current association when leaving to new BSS. this is
needed as old configuration and data were still stored in station table
and in low level driver, causing problems (e.g. 11n mlme) in new BSS
