irc: remove function irc_color_decode_for_user_entry

Since commits d03eb52d49 and
0c48b7ab8b, the IRC color codes are the
same in input line and messages, so the function
irc_color_decode_for_user_entry is not needed any more.
It was used only to decode colors when completing the command /topic
(with the channel topic).
