lttng-modules: update to 2.12.1
Drop backports. devupstream variant was incorrectly updated in a059fc67da4 (changed to 2.12, but without updating SRCREV), so revert it back to 2.11.2. Signed-off-by: Alexander Kanavin <alex.kanavin@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
