refactor(api): redundant `ml_mfp` check #26059

buf_ensure_loaded already checks `(buf->b_ml.ml_mfp != NULL)`. #25823

TODO:
- #10070 #13201 All buffer-related API functions except
  `nvim_buf_is_loaded` (and `nvim_buf_is_valid`?) should always call
  `buf_ensure_loaded`. Because the _common case_ is that plugins expect
  the buffer to "just work"—and for the uncomon, performance-sensitive
  case, the script can check `nvim_buf_is_loaded` to avoid implicitly
  loading a buffer.
- Update documentation to clarify the above semantics.
