qcacld-3.0: Create all SAP interface as ML type
On add virtual interface through cfg80211 ops, the params
to create adapter as ML will set for SAP mode.
However if SAP interface add is called internally in the
driver without setting the params to create the adapter
as ML type then, interface will be created in non-ML type
and ML SAP bringup fails.
Implicitly assume all SAP mode open adapter requests as ML type.
