smp: Move for loops to use arch_num_cpus instead of CONFIG_MP_NUM_CPUS

Browse source 
Change for loops of the form:

for (i = 0; i < CONFIG_MP_NUM_CPUS; i++)
   ...

to

unsigned int num_cpus = arch_num_cpus();
for (i = 0; i < num_cpus; i++)
   ...

We do the call outside of the for loop so that it only happens once,
rather than on every iteration.
