mm/nommu: use file_has_valid_mmap_hooks() helper
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().
Therefore, update the check for file operations supporting mmap() by using
the file_has_valid_mmap_hooks() helper function, which checks for either
f_op->mmap or f_op->mmap_prepare rather than checking only for f_op->mmap
directly.
