    Fix divide-by-zero panic when ASLR is enabled and superpages disabled

    When locating the anonymous memory region for a vm_map with ASLR
    enabled, we try to keep the slid base address aligned on a superpage
    boundary to minimize pagetable fragmentation and maximize the potential
    usage of superpage mappings.  We can't (portably) do this if superpages
    have been disabled by loader tunable and pagesizes[1] is 0, and it
    would be less beneficial in that case anyway.
