ixgbe: use EOPNOTSUPP instead of ENOTSUPP in ixgbe_ptp_feature_enable()
When the requested PTP feature is not supported,
ixgbe_ptp_feature_enable() returns -ENOTSUPP, causing userland programs
to get "Unknown error 524".
Since EOPNOTSUPP should be used when error is propagated to userland,
return -EOPNOTSUPP instead of -ENOTSUPP.
Fixes: 3a6a4edaa592 ("ixgbe: Hardware Timestamping + PTP Hardware Clock (PHC)")
