snapshot: Fix finding brick mount path logic
Backport of http://review.gluster.org/#/c/11060/
Previously while finding brick mount paths
of snap volume's bricks, we were taking brick order
into consideration. This logic fails when a brick is
removed or a tier is added.
Hence modifying the logic to look for the first
occurence of the word "brick" in the brick path.
From there we iterate till we find a '/'. The string
till the first '/' after we encounter the word brick
is the brick mount path.
