Please cherry-pick 5aa58c3a572b3e3 ("crypto: algif_aead - snapshot IV
for async AEAD requests") to 6.18. The earlier branches have this now,
but it's missing on 6.18.

Please cherry-pick 915b692e6cb723a ("crypto: pcrypt - Fix handling of
MAY_BACKLOG requests") to all LTS kernels.

Note: these bugs seem to be separate from the "copy.fail" bug.
