kernel-5.4: backport fd16931a2f51 for chacha neon

Without this patch, the chacha block counter is not incremented on neon
rounds, resulting in incorrect calculations and corrupt packets.

This also switches to using `--no-numbered --zero-commit` so that future
diffs are smaller.

-Subject: [PATCH 100/124] wireguard: send/receive: cond_resched() when
- processing worker ringbuffers
-
-commit 4005f5c3c9d006157ba716594e0d70c88a235c5e upstream.
-
-Users with pathological hardware reported CPU stalls on CONFIG_
-PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning
-these workers would never terminate. That turned out not to be okay on
-systems without forced preemption, which Sultan observed. This commit
-adds a cond_resched() to the bottom of each loop iteration, so that
-these workers don't hog the core. Note that we don't need this on the
-napi poll worker, since that terminates after its budget is expended.
