Subject: [PATCH 166/169] glusterd/svc: glusterd_svcs_stop should call
 individual wrapper function

glusterd_svcs_stop should call individual wrapper function to stop a
daemon rather than calling glusterd_svc_stop. For example for shd,
it should call glusterd_shdsvc_stop instead of calling basic API
function to stop. Because the individual functions for each daemon
could be doing some specific operation in their wrapper function.
