cluster/dht: Pass the req dict instead of NULL in dht_attr2()
Backport of: https://review.gluster.org/17085
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.
