[PATCH v14 04/16] Refactor quote_path_relative, remove unused params

[Jiang Xin <worldhello.net@gmail.com>]

After substitute path_relative() in quote.c with relative_path() from
path.c, parameters (such as len and prefix_len) are obsolete in function
quote_path_relative(). Remove unused parameters and change the order of
parameters for quote_path_relative() function.
