This is fixed in Ocata and above for Ubuntu. It looks like the upstream
tasks can also be moved to fix released.

Bug description:
There has been a recent regression in the nova-lvm tempest job. The
most recent passing run was on 2018-05-11 [1][2], so something
regressed it between then and yesterday 2018-05-15.
The build fails and the following trace is seen in the n-cpu log:

I think the failure is related to this change that merged on
2018-05-15:
https://review.openstack.org/567899
which moved the call of disk_api.get_disk_size(path) to be called for
all disk types instead of only for qcow2 and ploop. Based on the
surrounding code, only lvm.get_volume_size(path) should be called in
the case of lvm.
