smp: Optimize flush_smp_call_function_queue()
The call_single_queue can contain (two) different callbacks,
synchronous and asynchronous. The current interrupt handler runs them
in-order, which means that remote CPUs that are waiting for their
synchronous call can be delayed by running asynchronous callbacks.
Rework the interrupt handler to first run the synchonous callbacks.
