    in pmap_get_ptp(), if we need to allocate multiple new ptp levels
    and succeed in allocating some pages but fail to get them all,
    free any ptps we did allocate before returning.
    also, only consume kernel-reserve pages if pmap_enter()
    is called without PMAP_CANFAIL set, to help avoid deadlocking
    during high memory pressure.
