Which patch?  something equivalent to #5 is already present in 2:1.7.3-4

    https://sources.debian.org/src/cryptsetup/2:1.7.3-4/debian/cryptdisks.functions/#L765

Or do you mean `dmsetup remove_all` from #24?  Like for

/etc/init.d/lvm2 no longer deactivates LVs on shutdown since lvm2
≥2.02.84-3.  But I don't see which doing so should be the job of
/etc/init.d/cryptsetup instead.

Regardless, we won't be able to lock devices holding / or /usr.  AFAICT
that's where `/etc/init.d/cryptdisks stop` is choking with the repeated
“… is busy” messages.  For these devices the script might as well return
failure immediately and not try again.

Cheers,
