Andriy Gapon 3b50d59fef x86 topo_probe: do not probe smp topology if only one cpu is visible 
This could lead to a division by zero if hardware is multi-core and/or
multi-threaded, but for some (quite unusual) reason FreeBSD sees only
one logical processor.  This could happen, for example, if neither MADT
nor MP Table are presented by BIOS.

Also:
- assert in topo_probe_0x4 that BSP is accounted for
- neither cpu_cores nor cpu_logical should be zero after successful
  probing, so either being zero is an indication of failed probing
