  Add va_end calls to __ast_str_helper.

  According to the man page for stdarg(3),
  "Each invocation of va_copy() must be matched by a
  corresponding invocation of va_end() in the same
  function."

  There were several cases in __ast_str_helper where
  va_copy was not matched with a corresponding call
  to va_end.
