Fix fe_clean_rx to handle the changed frag_cache layout on newer kernels.
For kernels >= 6.13 the fragment cache needs to be converted from its
encoded_page value instead of using the old va field. Add an ifdef
to use frag_cache.encoded_page & PAGE_MASK and virt_to_page for those
kernels, keep the old path for older kernels.
