After introducing 'Add support for file I/O volume migration' via https://review.openstack.org/#/c/187270/ ,
new volume copy method _copy_volume_data() was added into manager.py and the generic volume migration
was changed to use this new function.

However, this method does not have efficient volume copy logic which was implemented in
copy_data_volume() of driver.py.(via https://review.openstack.org/#/c/183701/)

We should add same check logic into _copy_volume_data() to support efficient volume copy.
