[PATCH] let dmeventd unmount invalid snapshots (BZ 189462)

Hi again,

the somewhat delayed re-cast of the auto-umount patch is
attached. Changes since the last time:

- the umount itself is now outside the dmeventd lvm2 lock, which should
  mitigate the deadlock opportunities introduced by the umount
- we fork & exec real /bin/umount now, meaning that /etc/mtab is updated
  (well, if umount manages to update it, that is)

Yours,
   Petr.
