[RFC PATCH 3/6] ls-tree: optimize params of 'show_tree_common_default_long()'

[Teng Long <dyroneteng@gmail.com>]

From: Teng Long <dyroneteng@gmail.com>

Function 'show_tree_common_default_long' has 3 parameters:

  * struct strbuf *base
  * const char *pathname
  * const size_t baselen

And the struct 'show_tree_data' which was introduced in
'e81517155e0370ae5433d256046ab287bb10d04d' is:

  struct show_tree_data {
	       unsigned mode;
	       enum object_type type;
         const struct object_id *oid;
         const char *pathname;
         struct strbuf *base;
  };

Actually, the struct includes all the data that we need to pass to the
function, so we could make a small refactoring by using 'show_tree_data'
struct directly.
