cli: write 'volume rebalance' error message in xml format when

--xml is specified

When 'volume rebalance' encounters an error the cli prints the
error message in plain text independent of whether --xml is
specified. This throws off client application that expect xml
output (as mentioned in bz1026143).

Now, if the --xml flag is supplied, the cli print 'volume
rebalance' error messages in xml format.
