Fix in return value of afr_sh_mark_sources
afr_sh_mark_sources now returns: -1 if two wise subvols conflict (split-brain) 0 if all subvols are innocent (no self-heal needed) >0 if sources found Also, changes to callers of afr_sh_mark_sources to handle return value properly. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
