qcacld-3.0: Bypass the HE channel width fallback for SAP 

For STA connection in HE 160, HE160 MCS is validated
during the session creation. If the HE160 is invalid,
the connection falls back to 80MHz. But, this check needs
to be bypassed for SAP, because during session creation SAP
will not have the peer capability, so the HE160 MCS validation
needs to be bypassed.
