shutdown: share dm teardown with lvm

lvm is a chatty bitch and wants to tell all its friends about what it's
doing. Mostly this just goes poorly with udev, but now its lvmetad as
well. Use dmsetup as a shortcut and just tear down the volumes without
worrying about the needless accounting.

Guys? GUYS?!?! GUYS IM TEARING STUFF DOWN NOW!!!11!!!111

Fixes FS#32680.
