[PATCH v2 11/27] vfio/container: Convert functions to base container

[Zhenzhong Duan]

From: Eric Auger <eric.auger@redhat.com>

In the prospect to get rid of VFIOLegacyContainer refs
in common.c lets convert misc functions to use the base
container object instead:

vfio_devices_all_dirty_tracking
vfio_devices_all_device_dirty_tracking
vfio_devices_all_running_and_mig_active
vfio_devices_query_dirty_bitmap
vfio_get_dirty_bitmap
