qcacmn: Fix issue with is_primary flag in splitphy mode

Currently, for all link peers of ML peer, is_primary set as
true, since all link peers are attached to same PSOC.

But, FW and DP needs only one peer to be set primary.
So far, FW and DP are considering last peer created or last peer
assoc received as primary peer.

This method causing issue since the order is not guaranteed
between FW and DP layer.

So, added a change to set is_primary to one of the link peers
only
