s390/pageattr: Implement missing kernel_page_present()
[ Upstream commit 2835f8bf5530750c3381166005934f996a83ad05 ]
kernel_page_present() was intentionally not implemented when adding
ARCH_HAS_SET_DIRECT_MAP support, since it was only used for suspend/resume
which is not supported anymore on s390.
A new bpf use case led to a compile error specific to s390. Even though
this specific use case went away implement kernel_page_present(), so that
the API is complete and potential future users won't run into this problem.
