wlcore: save session_id per-link

Browse Source 
A new session_id is generated on link allocation.
it is saved in a global array and used later, on tx.

The new fw api adds new bcast/global_session_id
fields to start_role(ap) command, and a new session_id
field to add_peer command. align the driver with it.
