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.
