migration: sync all address spaces
Migrating a VM during reboot sometimes results in differences
between the source and destination in the SMRAM area.
This is because migration_bitmap_sync() only fetches from KVM
the dirty log of address_space_memory. SMRAM memory slots
are ignored and the modifications to SMRAM are not sent to the
destination.
