rmap: remove obsolete check from __page_check_anon_rmap()
When an anonymous page is inherited from a parent process, the
vma->anon_vma can differ from the page anon_vma. This can trip up
__page_check_anon_rmap, which is indirectly called from do_swap_page().
Remove that obsolete check to prevent an oops.
