Does commit 615d22a51c04856efe62af6e1d5b450aaf5cc2c0 "block: Fix __blkdev_issue_zeroout loop" fix the issue for you?
I crashed the 4.13-rc4 with the test above (blkdiscard -z on dm-crypt dev). Unfortunately I hadn't have my VM configured properly so the only info I got before it crashed was basically OOM. I'm going to play with it tomorrow and will let you know.
O.
