Description of problem:
======================
There is a type error in __dht_check_free_space function log message.

[2018-02-20 05:34:48.556248] W [MSGID: 109023] [dht-rebalance.c:962:__dht_check_free_space] 0-distrepx3-dht: data movement of file {blocks:7 name:(/1/linux-4.6.4/Documentation/device-mapper/era.txt) } would result in dst node (distrepx3-replicate-1:41274488) having lower disk space then the source node (distrepx3-replicate-2:41445560).Skipping file.

Message "then the source node" has to be corrected to "than the source node"

And we can remove the extra space before closing flower brace {blocks:7 name:(/1/linux-4.6.4/Documentation/device-mapper/era.txt) }

Version-Release number of selected component (if applicable):
3.12.2-4.el7rhgs.x86_64

Steps to Reproduce:
====================
1) create a gluster volume and start it.
2) FUSE mount on a volume and start IO.
3) Add bricks to the volume and, make sure that there is some space discrepancy 
4) start the rebalance without force option
gluster volume rebalance <vol> start 
5) Check the status of rebalance and make sure that some skipped files are there

Actual results:
================
Log message has typo at then
"lower disk space then the source node" 

Expected results:
=================
Fix typo.
