glusterd: search port from last_alloc to base_port
If a brick process is killed ungracefully then GlusterD wouldn't receive a
PMAP_SIGNOUT event and hence the stale port details wouldn't be removed out.
Now consider the following case:
1. Create a volume with 1 birck
2. Start the volume (say brick port allocated is 49152)
3. Kill the brick process by 'kill -9'
4. Stop & delete the volume
5. Recreate the volume and start it. (Now the brick port gets 49153)
6. Mount the volume
Now in step 6 mount will fail as GlusterD will provide back the stale port
number given the query starts searching from the base_port.
Solution:
To avoid this, searching for port from last_alloc and coming down to base_port
should solve the issue.
