glusterd: use string comparison for realpath checks in glusterd_is_brickpath_available

Backport of http://review.gluster.org/13258

glusterd_is_brickpath_available () used to call realpath() for checking the
whether the new brick path matches with the existing ones. The problem with this
is if the underlying file system is bad for any one of the existing bricks then
realpath() would fail and we wouldn't allow to create the new brick even if it
should be allowed.

Fix is to use string comparison with having a new field real_path in brickinfo
to store the absolute path
