Revert "glusterd: Allocate fresh port on brick (re)start"

This reverts commit 34899d7

Commit 34899d7 introduced a change, where restarting a volume or rebooting
a node result into fresh allocation of brick port. In production
environment generally administrator makes firewall configuration for a
range of ports for a volume. With commit 34899d7, on rebooting of node
or restarting a volume might result into volume start fail because
firewall might block fresh allocated port of a brick and also it will be
difficult in testing because of fresh allocation of port.
