Andreas Gruenbacher ec5ebfd1ce powerpc/kvm: Fix kvm_use_magic_page
commit 0c8eb2884a upstream.

When switching from __get_user to fault_in_pages_readable, commit
9f9eae5ce7 broke kvm_use_magic_page: like __get_user,
fault_in_pages_readable returns 0 on success.

Fixes: 9f9eae5ce7 ("powerpc/kvm: Prefer fault_in_pages_readable function")
