crush: make 'remove_root' idempotent

We might use 'crush link' to link same host into
different roots, which as a result can cause different
shadow trees reference same hosts too.

This means we may need to destory the same buckets(hosts, racks, etc.)
multiple times during rebuilding all shadow trees and hence 'remove_root'
shall be idempotent.
