cman init: fix start sequence error handling

Any daemon that fails to start would leave no traces.

the problem with cman init is that we need to handle multiple daemons
and tools. If one in the chain fails, we never reverted to the original
state of the system. This can indeed cause other issues.

Fix the init script to "stop" cman if any error happens during "start.

Resolves: rhbz#806002
