CVE-2026-89770

In the Linux kernel, the following vulnerability has been resolved:

iomap: don't free integrity payload that doesn't exist

fs bio integrity alloc might not allocate a bio integrity payload if PI verification is disabled on the block device. Check for that case before calling fs bio integrity free in iomap bio read folio range sync to avoid a NULL pointer dereferences.

Make the branch cover the PI verification as well - while fs bio integrity verify works without an integrity payload, it requires one to actually do useful work.
