iwlagn: fix "Received BA when not expected"

Need to use broadcast sta_id for management frames, otherwise we broke
BA session in the firmware and get messages like that:

"Received BA when not expected"

or (on older kernels):

"BA scd_flow 0 does not match txq_id 10"

This fix regression introduced in 2.6.35 during station management
code rewrite by:

commit 2a87c26bbe9587baeb9e56d3ce0b4971bd777643

    iwlwifi: use iwl_find_station less

Patch partially resolve:
https://bugzilla.kernel.org/show_bug.cgi?id=16691
However, there are still 11n performance problems on 4965 and 5xxx
devices that need to be investigated.
