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.

-Subject: [PATCH 3/4] Fix: Use vmalloc_sync_mappings on kernel 5.6 as well
-
-Upstream commit [1], that got rid of vmalloc_sync_all and introduced
-vmalloc_sync_mappings, is a v5.6 commit:
-$ git tag --contains 763802b53a427ed3cbd419dbba255c414fdd9e7c
-v5.6
-v5.6-rc7
-v5.7-rc1
-v5.7-rc2
-v5.7-rc3
-
-Extend the LINUX_VERSION_CODE check to v5.6 to fix the following warnings:
-...
-[  483.242037] LTTng: vmalloc_sync_all symbol lookup failed.
-[  483.257056] Page fault handler and NMI tracing might trigger faults.
-...

-Upstream-Status: Backport [https://github.com/lttng/lttng-modules/commit/da356b324dfc160e09b8966b691792037badf455]
