slirp: Fix queue walking in if_start

Another attempt to get this right: We need to carefully walk both the
fastq and the batchq in if_start while trying to send packets to
possibly not yet resolved hosts on the virtual network.

So far we just requeued a delayed packet where it was and then started
walking the queues from the top again - that couldn't work. Now we pre-
calculate the next packet in the queue so that the current one can
safely be removed if it was sent successfully. We also need to take into
account that the next packet can be from the same session if the current
one was sent and there are no other sessions.
