cramfs: fix incorrect physical page address calculation

Commit 21aa65bf82a7 ("mm: remove callers of pfn_t functionality")
incorrectly replaced the pfn with the physical address when calling
vmf_insert_mixed(). Instead the phys_to_pfn_t() call should have been
replaced with PHYS_PFN().

Found by inspection after a similar issue was noted in fuse virtio_fs.
