Request to cherry-pick 20401d1058f3f841f35a594ac2fc1293710e55b9 to v5.10 and v5.4

Hi all,

Commit 20401d1058f3f841f35a594ac2fc1293710e55b9("ipc: replace costly
bailout check in sysvipc_find_ipc()" fixes a high cve and optimizes the
costly loop by adding a checkpoint, which I think might be a good
candidate for the stable branches

Let me know what you think
