MFC 250219:
Fix two bugs in the current NUMA-aware allocation code:
- vm_phys_alloc_freelist_pages() can be called by vm_page_alloc_freelist()
  to allocate a page from a specific freelist.  In the NUMA case it did not
  properly map the public VM_FREELIST_* constants to the correct backing
  freelists, nor did it try all NUMA domains for allocations from
  VM_FREELIST_DEFAULT.
- vm_phys_alloc_pages() did not pin the thread and each call to
  vm_phys_alloc_freelist_pages() fetched the current domain to choose
  which freelist to use.  If a thread migrated domains during the loop
  in vm_phys_alloc_pages() it could skip one of the freelists.  If the
  other freelists were out of memory then it is possible that
  vm_phys_alloc_pages() would fail to allocate a page even though pages
  were available resulting in a panic in vm_page_alloc().
