inet: factor out inet_send_prepare()
The same code is replicated verbatim in multiple places, and the next patches will introduce an additional user for it. Factor out a helper and use it where appropriate. No functional change intended. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
