AZL-110957: CVE-2026-99067 affecting package kernel 6.6.157.1-1

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

btrfs: scrub: fix localroot reference leak in scrubprintwarninginode()

When pathsfrominode() fails, scrubprintwarninginode() jumps to err without dropping the reference taken by btrfsgetfsroot(), leaking a reference to the root every time path resolution fails while printing scrub warnings. Every other error and success path of the function drops the reference.

Drop the reference on the pathsfrominode() failure path too.
