commit 70fd1966c93bf3bfe3fe6d753eb3d83a76597eef upstream.
In find_asymmetric_key(), if all NULLs are passed in the id_{0,1,2}
arguments, the kernel will first emit WARN but then have an oops
because id_2 gets dereferenced anyway.
Add the missing id_2 check and move WARN_ON() to the final else branch
to avoid duplicate NULL checks.
