Fix: Volume create should fail when a node is down

Earlier while volume creation randomly selected one node
and stopped gluster but the volume type used in the test
is pure distribute and default glusto config takes 4
bricks.
With the fix now randomly selecting only first
4 nodes for volume creation and it will fail.
