erts: Fix race bug between export fun creation and code loading
Symptom: SEGV crash on ARM in delete_code() -> export_list().
Could probably happen on other machines as well.
Problem: Staging export table was iterated in an unsafe way
while an entry was added for a new export fun.
Solution: Correct write order and some memory barriers.
