Fix UDP for memcache with native stack
memcached: apps/memcached/memcached.cc:807:
void memcache::assert_resolved(future<>): Assertion `f.available()'
failed.

UDP path relied on the fact that handle() could not block, because
the output stream does not block, and passed references to variables
which live on stack. Since you now can block in handle_get(), this
no longer holds. We should chnage that, ie allocate conversation
state like we do in TCP.
