I have no idea, since I don't really understand the details.  Which part
is responsible to actually create the device nodes?  AFAIK, cryptsetup
only triggers the creation via writing to /dev/mapper/control and udev
creates the files.

When I was googling for the error message, I found several discussions
about race conditions with LVM+udev which caused similar symptoms.

I also found some suggestions like:

  sudo apt-get --reinstall install linux-generic initramfs-tools

and

  sudo cp /etc/udev/rules.d/25-dmsetup.rules.pkg-dist /etc/udev/rules.d/25-dmsetup.rules

but they did not help, either :-(
