builtin/notes: refactor note file path into struct note_data

Browse source 
Move the 'path' variable from create_note() and into the
note_data struct. Unify cleanup of note_data objects with
a free_note_data() function.

This might not make too much sense on its own, but it makes the
future refactoring of create_note() considerably cleaner.
