  [MemProf] Fix handling of recursive edges during func assignment (#129066)

When we need to reclone other callees of a caller node during function
assignment due to the creation of a new function clone, we need to skip
recursive edges on that caller. We don't want to reclone the callee in
that case (which is the caller), which isn't necessary and also isn't
correct from a graph update perspective. It resulted in an assertion and
in an NDEBUG build caused an infinite loop.
