glusterd: persist brickinfo's port change into glusterd's store

Problem:
Consider a case where node reboot is performed and prior to reboot
brick was listening to 49153. Post reboot glusterd assigned 49152
to brick and started the brick process but the new port was never
persisted. Now when glusterd restarts glusterd always read the port
from its persisted store i.e 49153 however pmap signin happens with
the correct port i.e 49152.

Fix:
Make sure when glusterd_brick_start is called, glusterd_store_volinfo is
eventually invoked.
