trace,smp: Trace all smp_function_call*() invocations

(Ab)use the trace_ipi_send_cpu*() family to trace all
smp_function_call*() invocations, not only those that result in an
actual IPI.

The queued entries log their callback function while the actual IPIs
are traced on generic_smp_call_function_single_interrupt().
