QObject: fix memory order on load/store of signal spy callback set
QSignalSpyCallbackSet is a set of pointers, so when we store a pointer
to it for later dereferencing, we need to use a release fence for the
store and a corresponding acquire on load, lest the two don't
synchronize with each other and we end up with a data race.
