Log message:
	Fix clvmd init script return code when executed as non-root user.
	
	clvmd daemon itself does the right thing when invoked as non-root, by
	returning 4.
	
	The patch removes the use daemon function from
	/etc/rc.d/init.d/functions that??s unnecessary and has th bad habit to
	mask the return codes from the real daemon.
	
	Add a simple and generic check to see if clvmd is executed by root or not.
	
	Our stop/reload/restart paths in the init script are complex and not all
	the tools involved in the process are guaranteed to return 4 if executed
	by non-root against a process that??s running as root (for example kill
	-TERM will return -1 and parsing the output to catch the error is
	suboptimal at best).
