glusterd: add check in remove-brick start variant
The 'start' variant of the remove-brick command only applies at the dht
level wherein we can remove all the bricks of a sub-volume (and remove
multiple such sub-volumes) but not select bricks of it.
This patch disallows removing individual replica bricks of multiple
sub-volumes (i.e. reducing the replcia count of the volume) using
remove-brick 'start'. The preferred method for such an operation is to use
commit force.
This patch also reverts the check to prevent removal of bricks from a
replicate volume (commit 0d415f7)
