tests/shard: fix tests/bugs/shard/unlinks-and-renames.t failure

on rhel8 machine cleanup of shards is not happening properly for a
sharded file with hard-links. It needs to refresh the hard link count
to make it successful

The problem occurs when a sharded file with hard-links gets removed.
When the last link file is removed, all shards need to be cleaned up.
But in the current code structure shard xlator, instead of sending a lookup
to get the link count uses stale cache values of inodectx. Therby removing
the base shard but not the shards present in /.shard directory.

This fix will make sure that it marks in the first unlink's callback that
the inode ctx needs a refresh so that in the next operation, it will be
refreshed by looking up the file on-disk.
