glusterd: do not create .glusterfs/indices

glusterd shouldn't concern itself with creating directories specific to
certain xlators.

The index xlator will now proceed creating './glusterfs/indices' dir
only if the parent '.glusterfs' directory exists, which still fixes the
original problem reported i.e 'volume start force' command shouldn't
create brick path if it doesn't exist (BUG 1457202)

This reverts most of the changes done by the commit
b58a15948fb3fc37b6c0b70171482f50ed957f42
