fix: lvm: Handle cleanup after unreadable files

Browse source 
Before this commit, since restic backup exits with status 3 if it
cannot read one or more files, the LVM snapshot wasn't being cleaned
up.

Now, specially handle the 3 exit status; also, unequivocally perform
the LVM cleanup when finished.
