rt2x00: Make rt2x00_queue_entry_for_each more flexible
Allow passing a void pointer to rt2x00_queue_entry_for_each which in
turn in provided to the callback function.
Furthermore, allow the callback function to stop processing by returning
true. And also notify the caller of rt2x00_queue_entry_for_each if the
loop was canceled by the callback.
No functional changes, just preparation for an upcoming patch.
