qcacld-3.0: Refine lim_is_mlo_conn

Although mlo connection is mandatory feature for 11be, to simplify feature
verification, 11be can be supported without MLO feature.

MLO connection can only be treated as enabled between mlo ap and sta with
mlo IE. This is the same check polity when setting mlo flags in peer
object.
