CVE-2026-72100: dm-integrity: fix a bug if the bio is out of limits
In the Linux kernel, the following vulnerability has been resolved:
dm-integrity: fix a bug if the bio is out of limits
If dmintegritychecklimits fails, the code would exit with DMMAPIOKILL. However, the range would be already locked at this point, and it wouldn't be unlocked, resulting in a deadlock. Let's move the limit check up, so that when it exits, no resources are leaked.
