vfio: Add Error** argument to vfio_devices_dma_logging_start()

This allows to update the Error argument of the VFIO log_global_start()
handler. Errors for container based logging will also be propagated to
qemu_savevm_state_setup() when the ram save_setup() handler is executed.
Also, errors from vfio_container_set_dirty_page_tracking() are now
collected and reported.

The vfio_set_migration_error() call becomes redundant in
vfio_listener_log_global_start(). Remove it.
