Modified Files:
        src/sys/arch/x86/x86: pmap_tlb.c

Log Message:
Operation pmap_tlb_processpacket() uses x86_ipi(.., LAPIC_DEST_ALLEXCL, ...)
when cpuset "target" equals "kcpuset_running".  During boot, while some CPUs
are not running yet, this will result in more IPI interrupts than expected
and "pmap_tlb_pendcount" related KASSERTs fire.

Compare the cpuset "target" against "kcpuset_attached", as this set represents
the CPUs LAPIC_DEST_ALLEXCL will notify.

Should fix PR port-amd64/47437
