mm/filemap: introduce generic_file_*_mmap_prepare() helpers
Since commit c84bf6dd2b83 ("mm: introduce new .mmap_prepare() file
callback"), the f_op->mmap() hook has been deprecated in favour of
f_op->mmap_prepare().
The generic mmap handlers are very simple, so we can very easily convert
these in advance of converting file systems which use them.
This patch does so.
