igw: fix image removal during purge

We were not passing in the ceph conf info into the rbd image removal
command, so if the clustername was not the default igw purge would fail
due to the rbd rm command failing.

This just fixes the bug by passing in the ceph conf info which has the
clustername to use.

This fixes Red Hat bugzilla:
