    cluster/dht: Pass the req dict instead of NULL in dht_attr2()

    This bug was causing VMs to pause during rebalance. When qemu winds
    down a STAT, shard fills the trusted.glusterfs.shard.file-size attribute
    in the req dict which DHT doesn't wind its STAT fop with upon detecting
    the file has undergone migration. As a result shard doesn't find the
    value to this key in the unwind path, causing it to fail the STAT
    with EINVAL.

    Also, the same bug exists in other fops too, which is also fixed in
    this patch.
