The DRBD uses underlying device so code should prefer top
device if duplicate is found.
Patch also introduce
dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.
See https://bugzilla.redhat.com/show_bug.cgi?id=530881
for full problem description.
