After migration, the image labels will be removed in the src host (on
success) or the dst host (on failure). However, if we migrate using
shared fs and remove image labels after migration in one host, the image
labels will also lost in another host, which leads to that the ownership
of the image will be restore to root:root instead of the origin
ownership when shutting down the VM. Hence, don't remove image labels
after migration with shared fs.
