You're right. It's impossible to close the dm-crypt mapping for
encrpyted root during shutdown process as the root device would need to
be unmounted beforehand.

There's no easy solution to fix this instead of using a initramfs which
is executed just after root device has been unmounted. To my knowledge,
this is not implemented for sysvinit shutdown process in Debian yet.
Tagging the bug as wontfix for that reason.
