udp: Move sending pasta tap frames to the end of udp_sock_handler()

udp_sock_handler() has a surprising difference in flow between pasta and
passt mode: For pasta we send each frame to the tap interface as we prepare
it.  For passt, though, we prepare all the frames, then send them with a
single sendmmsg().

Alter the pasta path to also prepare all the frames, then send them at the
end.  We already have a suitable data structure for the passt case.  This
will make it easier to abstract out the tap backend difference in future.
