sched: check for SD_SERIALIZE atomically in rebalance_domains()

Nothing really serious here, mainly just a matter of nit-picking :-/

For CONFIG_SCHED_DEBUG && CONFIG_SYSCT configs, sd->flags can be altered
while being manipulated in rebalance_domains(). Let's do an atomic check.
We rely here on the atomicity of read/write accesses for aligned words.
