qcacmn: Fix roam abort for 2nd sta connect

During wlan0 vdev0 roaming, before roam sync received,  2nd sta wlan1
vdev2 connect req came, disabled RSO of vdev0, so vdev0 roam aborted, and
disconnected.

To fix it, serialize roaming disable during connect too, don’t disable
roaming of other connected sta until serialization allowed in
wlan_serialization_activate_cmd ->cm_connect_active
