PureISCSIDriver's log statements had a bad merge resolution

[Patrick East]

Changes from:

https://git.openstack.org/cgit/openstack/cinder/commit/?id=dbd111f87deb9a4636e466b9d75c76bf981cf8e5
https://review.openstack.org/134918

reverted the fixes to our log statements from a slightly early change:

https://git.openstack.org/cgit/openstack/cinder/commit/?id=1ebe1bddd0a02e9efaa05c8ec9d71a299b6877e1

We should put back in the changes that got reverted so we do not use .format() anywhere in the code... This will address the issues raised here:

    Fixup regressions in PureISCSIDriver log statements.

    There were some conflicting patches that went in to fix i18n helpers,
    and in the merge resolution we lost some changes that previously removed
    all uses of .format() from the driver. This puts back in the updated
    log statements originally added in
