    glusterd: search port from last_alloc to base_port

    Backport of http://review.gluster.org/14268

    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.
