vfio/migration: Store VFIO migration flags in VFIOMigration

VFIO migration flags are queried once in vfio_migration_init(). Store
them in VFIOMigration so they can be used later to check the device's
migration capabilities without re-querying them.

This will be used in the next patch to check if the device supports
precopy migration.
