mac80211: make uapsd_* keys per-vif
uapsd_queues and uapsd_max_sp_len are relevant only for managed interfaces, and can be configured differently for each vif. Move them from the local struct to sdata->u.mgd, and update the debugfs functions accordingly. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
