Zenghui Yu 1370d61ae3 memory: Skip dirty tracking for un-migratable memory regions ...

It makes no sense to track dirty pages for those un-migratable memory
regions (e.g., Memory BAR region of the VFIO PCI device) and doing so
will potentially lead to some unpleasant issues during migration [1].

Skip dirty tracking for those regions by evaluating if the region is
migratable before setting dirty_log_mask (DIRTY_MEMORY_MIGRATION).
