dgram: remove unnecessary fd property from Socket
It seems the property socket.fd
is used long before for the compatibility reason but it's not used anymore.
It's also not documented in docs so that it's not a public api/property.
Keep the property also makes the code a bit confusing as socket._handle.fd
is the actual property representing fd.
