But it also changes when the code to get the stats is run. Previously it
was always run for active migration (and doing so would report an error
on the destination host) while after this patch the code is specifically
run only on the source host. This patch doesn't change anything if 8/12
is unchanged, but the change doesn't make a lot of sense without 8/12.

Also depending on the changes done in 6/12, there may be no need
separate the code at all.
