crypto: ecrdsa - fix unknown OID check in ecrdsa_param_curve
The ->curve_oid check in ecrdsa_param_curve() rejects the valid enum
value 0 (OID_id_dsa_with_sha1), but look_up_OID() returns OID__NR on
lookup failure. Compare ->curve_oid with OID__NR instead to ensure that
only unknown OIDs return -EINVAL.
