mac80211: Always check rates and capabilities in mesh mode
In mesh mode there is a race between establishing links and processing rates and capabilities in beacons. This is very noticeable with slow beacons (e.g. beacon intervals of 1s) and manifested for us as stations using minstrel when minstrel_ht should be used. Fixed by changing mesh_sta_info_init so that it always checks rates and such if it has not already done so.
