chs bb0c381fb9 two changes to prevent the kernel's pmap from being locked recursively
via interrupts:

(1) pmap_map_ptes() and pmap_unmap_ptes() don't need to do anything to
    map the kernel's pmap, since all pmaps contain the kernel's PTPs.
    this fixes interrupt-context calls to pmap_extract().
(2) pmap_kenter_*() and pmap_kremove() no longer adjust the kernel pmap's
    resident and wired counters.
