x86/smp: Remove pointless duplicated interrupt code
Two NOP5s are really a good tradeoff vs. the unholy IDT switching mess,
which duplicates code all over the place. The rescheduling interrupt gets
optimized in a later step.
Make the ordering of function call and statistics increment the same as in
other places. Calculate stats first, then do the function call.
