There were already assertions that we were not passing a tail page
to error_remove_page(), so make the compiler enforce that by converting
everything to pass and use a folio.

virt/kvm/guest_memfd.c exists only in the KVM tree (and hence
linux-next).  So I assume Stephen will use the change from this patch
when doing his resolution.

Guilty of developing against linux-next ;-)  Sorry, I didn't notice it
depended on something else; thanks for alerting Stephen.
