Log: Fix interrupt load balancing regression, introduced in revision 222813, that left all un-pinned interrupts assigned to CPU 0. sys/x86/x86/intr_machdep.c: In intr_shuffle_irqs(), remove CPU_SETOF() call that initialized the "intr_cpus" cpuset to only contain CPU0. This initialization is too late and nullifies the results of calls the intr_add_cpu() that occur much earlier in the boot process. Since "intr_cpus" is statically initialized to the empty set, and all processors, including the BSP, already add themselves to "intr_cpus" no special initialization for the BSP is necessary.
