cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_station

Browse Source 
The information of the peer's capabilities is required for the driver
to perform TDLS Peer UAPSD operations. This information of the peer is
passed by the supplicant using NL80211_CMD_SET_STATION command. This
commit enhances the function nl80211_set_station to pass this
information of the peer to the driver in case this command is used
with the TDLS peer STA.

In addition, make the HT/VHT capability configuration handled more
consistently for other STA cases (reject both instead of just HT).
