TDLS: Add peer as a STA during link setup

Browse source 
Before commencing setup, add a new STA entry to the driver representing
the peer. Later during setup, update the STA entry using information
received from the peer.

Extend sta_add() callback for adding/modifying a TDLS peer entry and
connect it to the TDLS state machine. Implement this callback for the
nl80211 driver and send peer information to kernel.

Mark TDLS peer entries with a new flag and translate it to a
corresponding nl80211 flag in the nl80211 driver.

In addition, correct TDLS related documentation in the wpa_driver_ops
structure.
