docs/migration: Update postcopy bits

We have postcopy recovery but not reflected in the document, do an update
for that.

Add a very small section on postcopy preempt.

Touch up the pagemap section, dropping the unsent map because it's already
been dropped in the source code in commit 1e7cf8c323 ("migration/postcopy:
unsentmap is not necessary for postcopy").

Touch up the postcopy section to remove "network connection" failures as
downside, because now it's not fatal and can be recovered.  Suggested by
Laszlo.
