mt76: mt7615: fix hw_scan with ssid_type for specified SSID only

Fix hw_scan with ssid_type for specified SSID only

The definition for ssid_type in current firmware is that
ssid_type BIT(2) set actually for specified SSID + wildcard SSID.
ssid_type BIT(2) and ssid_type_ext BIT(0) both set actually for
specified SSID only;
