power: smb5: Fix Type-C mode with non-compliant shorted cable



When a QC adapter is inserted with non-compliant shorted cable,
SMB5 charger shows shorted cable without Rp value (rp-std,
med or high), as a result, SW reports non typec connection.

Fix it by reporting 'Type-C non-compliant' instead.
