tests: Use pointers in calls to g_atomic_pointer_compare_and_exchange()

Browse Source 
Don’t pass integers; it’s not type-safe. The macro version of
`g_atomic_pointer_compare_and_exchange()` used to erroneously accept
integers, but they would have the wrong width on some platforms.

Changes originally investigated and suggested by Ting-Wei Lan.
