This makes lvmlockd removal steps for dlm VGs closely match sanlock VGs. Because dlm lockspaces are not required to be stopped on all hosts before vgremove, there is an extra bit for dlm lockspaces, where a flag is set in the VG lock lvb indicating that the VG was removed. If other hosts happen to use the VG lock they will see this flag and stop their lockspace.
