qcacld-3.0: Fix assert for wrong mlo_vdev count

Current issue:
When roam from legacy to MLO, set vdev MLO flags but not increase the
mlo_vdev count, when disconnect, decrease mlo_vdev count, assert will
happen.
Solution:
Use API wlan_vdev_mlme_set_mlo_vdev and wlan_vdev_mlme_clear_mlo_vdev to
set MLO vdev flag.
