page_fault_process_memory_range: Disable COW for VM region with zeroobj
...
This fixes ostest-mem_limits.001 which tries to anonymous-mmap 95% of
total memory. It reports a failure because:
(1) McKernel tries to allocate physically contiguous area and
fails
(2) It turns on demand-paging
(3) It tries to obtain a page from zeroobj and fails
(4) It allocates a new page
(5) It performs COW on the page, which is unnecessary
