cramfs: fix incorrect physical page address calculation

Browse source

[ Upstream commit 20a8e0454d ]

Commit 21aa65bf82 ("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.
