lttng-modules: fix build against v5.10+

lttng-modules doesn't currently build against the lastest 5.10-rc
versions.

Upstream lttng does have fixes for the issues, but hasn't done a
release that contains them yet. There are other patches on the
2.12.x branch, but I've skipped them for now as they aren't
necessary for 5.10 builds, and can be picked up with the next
full update.

We also bump the dev-upstream hash to make them easier to pickup
for those building from git.

+Subject: [PATCH 10/19] fix: ext4: fast commit recovery path (v5.10)
+
+See upstream commit :
+
+  commit 8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2
+  Author: Harshad Shirwadkar <harshadshirwadkar@gmail.com>

+
+    ext4: fast commit recovery path
+
+    This patch adds fast commit recovery path support for Ext4 file
+    system. We add several helper functions that are similar in spirit to
+    e2fsprogs journal recovery path handlers. Example of such functions
+    include - a simple block allocator, idempotent block bitmap update
+    function etc. Using these routines and the fast commit log in the fast
+    commit area, the recovery path (ext4_fc_replay()) performs fast commit
+    log recovery.
