Subject: [PATCH 322/335] glusterd: display correct rebalance data size after
 glusterd restart

Problem: After completion of rebalance, if glusterd is restarted,
rebalance status displays wrong rebalance data size in its output.

Cause: While glusterd restoring the information from /var/lib/glusterd/
into its memory, glusterd fetches rebalance_data from
/var/lib/glusterd/vols/volname/node_state.info. This value is
converted into an integer using atoi(), which is returning
incorrect value for larger values.

Solution: use sscanf() instead of atoi() to convert string to
integer(in this case it is unsigned long)
