John Baldwin c9107e85d9 Fix a silly bogon which prevented all the CPUs that are tagged as interrupt 
receivers from being given interrupts if any CPUs in the system were not
tagged as interrupt receivers that I introduced when switching the x86
interrupt code to track CPUs via FreeBSD CPU IDs rather than local APIC
IDs.  In practice this only affects systems with Hyperthreading (though
disabling HTT in the BIOS would workaround the issue) as that is the only
case currently where one can have CPUs that aren't tagged as interrupt
receivers.  On a Dell SC1425 test box with 2 x Xeon w/ HTT (so 4 logical
CPUs of which 2 were interrupt receivers) the result was that all
device interrupts were sent to CPU 0.
