jammy:linux bpf selftest do not build

[Roxana Nicolescu]

SRU Justification:

[Impact]

* bpf selftest do not compile. See the error below.
Commit "bpf: Allow reads from uninit stack" introduced the usage of '__failure',
without bringing the commit where this is defined.
This prevents us from running other tests and it also affects the netselfts because they are dependant on it.

[Fix]

* While discussing with upstream a revert of this commit will be the fix for now.

[Test Plan]

* Revert, build the kernel, run the ubuntu_bpf_selftests and see it they build.

This bug is awaiting verification that the linux/5.15.0-121.131 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux' to 'verification-done-jammy-linux'. If the problem still exists, change the tag 'verification-needed-jammy-linux' to 'verification-failed-jammy-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
