TDLS: Pass peer's AID information to kernel

Browse source 
The information of the peer's AID is required for the driver to
construct partial AID in VHT PPDU's. Pass this information to the driver
during add/set station operations (well, as soon as the information is
available, i.e., with set station operation currently).
