dht/rebalance: Do not allow rebalance when gfid mismatch found

Due to race condition, it may so happen that, gfid obtained
in readdirp and gfid found by lookup are different for a given
name. in that case do no allow the rebalance.

Readdirp of an entry will bring the gfid, which will be stored
in the inode through inode_link, and when lookup is done and
gfid brought by lookup is different from the one stored in the
inode, client3_3_lookup_cbk will return ESATLE and error will be
captured by rebalance process.
