			This is the 2nd patch to unbreak postcopy recovery.
Let's unify the migration_incoming_process() call at a single place
rather than calling it in connection setup codes.  This fixes a problem
that we will go into incoming migration procedure even if we are trying
to recovery from a paused postcopy migration.
Fixes: 36c2f8be2c ("migration: Delay start of migration main routines")
