tier/dht: Ignoring replica for migration counting
We used to count replica files for migration counting even though they were ignore for migration as the replica brick didnt have the ownership (as per the replication xlator either AFR/EC). As a result the number of files migrated would show a wrong count, i.e each replicated file would be counted 1 + number of replica. This patch ignores such cases.
