crush: fix class_is_in_use()

A class can be considered as in-use only if it is referenced by
any of the existing crush rules.

The patch also makes the output more human readable. For example:

./bin/ceph osd crush rule create-replicated myrule default host ssd
./bin/ceph osd crush class rm ssd
Error EBUSY: class 'ssd' still referenced by crush_rule 'myrule'
