mm/page_alloc: remove a couple of VM_BUG_ON()st

Browse Source 
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.
