[PATCH v3 4/4] mm/page_alloc: remove a couple of VM_BUG_ON()st

[Brendan Jackman <jackmanb@google.com>]

VM_BUG_ON() is out of favour and on the way to removal, since I recently
touched alloc_pages_node_noprof() I am removing that invocation, and
also removing the __folio_alloc_node_noprof() one for consistency. If
this precondition is violated, the system will soon crash anyway.
