smp: Wait only if work was enqueued
Whenever work is enqueued for a remote CPU, smp_call_function_many_cond()
may need to wait for that work to be completed. However, if no work is
enqueued for a remote CPU, because the condition func() evaluated to false
for all CPUs, there is no need to wait.
Set run_remote only if work was enqueued on remote CPUs.
Document the difference between "work enqueued", and "CPU needs to be
woken up"
