shutdown, umount: use verbs consistently
Mounts are "unmounted".
Swaps are "deactivated", not "turned off" nor "disabled".
Loop and DM devices are "detached", not "deleted".
Especially the deleting sounded a bit scary.

commit bce93b7ac7642426039863493694d8c12812e2a7

shutdown, umount: logging improvements
In bugreports about hangs during the late shutdown we are often missing
important information - what were we trying to unmount/detach when it hung.
Instead of printing what we successfully unmounted, print what we are
going to unmount/detach. And add messages to mark the completion of
categories (mount/swap/loop/DM).

umount: fix check for DM changed
delete_dm() returns 0 on success. The check for "r > 0" was likely
a copy&paste error from the loopback code where "r > 0" makes sense.

shutdown: downgrade a warning
All messages of the kind "not all done, %d left" are log_info, except
the one for DM devices. Make it info too.
