features/shard: Fix unlink failure due to non-existent shard(s)
Unlink of a sharded file with holes was leading to EINVAL errors
because it was being wound on non-existent shards (those blocks that
fall in the hole region). loc->inode was NULL in these cases and
dht_unlink used to fail the FOP with EINVAL for failure to fetch
cached subvol for the inode.
The fix involves winding unlink on only those shards whose corresponding
inodes exist in memory.
