[C11] Correct global atomic pointer initialization from an integer constant

This is a follow-up to 2e275e24355cb224981f9beb2b026a3169fc7232 and
1395cde24b3641e284bb1daae7d56c189a2635e3 which corrects a missed case:
initializing an _Atomic(T *) from a null pointer constant in the form
of the integer literal 0.

Fixes https://github.com/llvm/llvm-project/issues/63550
