dht/rebalance : Fixed rebalance failure
The rebalance process determines the local subvols for the
node it is running on and only acts on files in those subvols.
If a dist-rep or dist-disperse volume is created on 2 nodes by
dividing the bricks equally across the nodes, one process might
determine it has no local_subvols.
When trying to update the commit hash, the function attempts to
lock all local subvols. On the node with no local_subvols the dht
inode lock operation fails, in turn causing the rebalance to fail.
In a dist-rep volume with 2 nodes, if brick 0 of each replica
set is on node1 and brick 1 is on node2, node2 will find that it has
no local subvols.
