tcp: factor out tcp_build_frag()
Will be needed by the next patch, as MPTCP needs to handle directly the error/memory-allocation-needed path. No functional changes intended. Additionally let MPTCP code access the tcp_remove_empty_skb() helper. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
