qcacmn: Use seperate event for HO/roaming disconnect for old AP

Use seperate event for HO/roaming disconnect for old AP, as
if a disconnect is received during roaming, the state is moved
to disconnect and thus WLAN_CM_SM_EV_DISCONNECT_DONE is handled
as a normal disconnect and does not clean up the roaming
contexts in VDEV and peer.
