mgmt/glusterd: Set task op at the time of task-id set

Problem:
If a remove-brick start is executed on m1 with brick from m2
on local subvolume no rebalance process is launched. Because of
this volinfo->rebal.op is not set. This leads to volume status
failures.

Fix:
Set rebal.op even when the reblance process is not started.
