[Libvirt-cim] [PATCH 3/3] schema: Fix class removal with Pegasus

[Viktor Mihajlovski]

In provider de-registration step, the provider-register.sh
script is attempting to delete all libvirt-cim classes from
the Pegasus repository. Pegasus refuses to delete classes
if it still has child classes in the repository.
While the MOF files are processed in reverse order, the classes
were still deleted in their original order, which can fail due
to inter-class dependencies.
Changed to reverse the class deletion order on a per MOF
file base.
