ethtool: fix reference leak in ethnl_set_privflags()
Andrew noticed that some handlers for *_SET commands leak a netdev
reference if required ethtool_ops callbacks do not exist. One of them is
ethnl_set_privflags(), a simple reproducer would be e.g.
ip link add veth1 type veth peer name veth2
ethtool --set-priv-flags veth1 foo on
ip link del veth1
Make sure dev_put() is called when ethtool_ops check fails.
