[ Upstream commit 04a8a3d0a73f51c7c2da84f494db7ec1df230e69 ]
The slow path for traced system call entries accessed a wrong memory location to get the number of the maximum allowed system call number. Renumber the numbered "local" label for the correct location to avoid collisions with actual local labels.
