[Attributor][FIX] AACallEdges, fix propagation error.

This patch fixes a error made in 2cc6f7c8e108. That patch
added a call site position but there was a small error with the way
the presence of a unknown call edge was being propagated from call site
to function. This patch fixes that error. This error was effecting some
AMDGPU tests.
