qcacmn: Do not reset linkid for bridge vap

Link ID for the bridge vap is set during creation.
However during mlo ap vdev attach, it gets overwritten by 0.

Due to this, during 2.4 GHz link removal using ml-reconfig,
2.4 GHz linkid and bridge vap as primary vaps linkid matches
which leads to full disconnection of the peer.

To fix this, retain previously set linkid for bridge vap.
