glusterd: Always copy old brick ports when importing

  Backport of ecf6243 from master.
When an updated volinfo is imported in, the brick ports from the old
volinfo should be always copied.

Earlier, this was being done only if the old volinfo was stopped and
new volinfo was started. This could lead to brick ports chaging when the
following sequence of steps happened.
- A volume is stopped
- GlusterD is stopped on a peer
- The stopped volume is started
- The stopped GlusterD is started
This sequence would lead to bricks on the peer with re-started GlusterD
to get new ports, which could break firewall rules and could prevent
client access. This sequence could be hit when enabling management
encryption in a Gluster trusted storage pool.
