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.
