AP MLD: Assign link ID during BSS creation

Browse source 
Link ID was assigned when BSS is going through setup and the driver
interface init. Later if interface is disabled and enabled again, setup
BSS is called which will give a new link ID to it. However, Link ID
should be same for a BSS affliated to an AP MLD for the full lifetime of
the BSS.

Hence, assign the link ID during BSS creation itself. And it will remain
until BSS entry is completely freed. Hence, link ID will not change as
part of disable/enable.

Also, since link ID would be decided now, it will help in creating link
level control sockets in a subsequent patch.
