[PATCH] fix some issues in clvmd initscript

[Milan Broz <mbroz@redhat.com>]

- if daemon is already running, do nothing (and not reactivate VGs)

- always explicitly return exit code in reload()

- fix restart() so it really tries full start & stop and returns exit code
  if clvmd -S fails and also touch lockfile afterwards
