glusterd: Fixed glusterd_brick_create_path algo.

- check if any prefix of the brick path has "trusted.gfid"
  or "trusted.glusterfs.volume-id" set.
- set trusted.glusterfs.volume-id on the bricks as soon as
  its induction into the volume is settled. Earlier, the setting of
  "volume-id" used to happen during the first run of the brick process,
  leaving of window for bricks part of one volume to be (ab)used by another
  volume inadvertently.
- removed creation of brick directory (if missing), during start volume force.
  This is to avoid directory creation as part 'force'ful starting of volume
  and leave the responsibility with the user, who understands the
  'availability' of the export directory (brick) better.
