Rao, Lei May 24, 2022, 6:18 a.m. UTC 
The statistics of bytes transferred conceptually belong to The VFIO live
migration framework, and should not belong to any specific implementation
such In-Band approach, so move it out from vfio_migration_region_save_buffer(),
which makes it easier to add other implementations.
