kvm: book3s: rename lookup_linux_pte() to lookup_linux_pte_and_update()
lookup_linux_pte() is doing more than lookup, updating the pte, so for clarity it is renamed to lookup_linux_pte_and_update() Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Reviewed-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
