Remove nonsensical size check in mutt_choose_charset()

The charsets parameter is being tokenized by the : delimeter.

The checks against ENCWORD_LEN_MAX and ENCWORD_LEN_MIN make no sense,
and appear to be the result of a large merge a very long time ago
(changeset cb27682966d5).

I can only guess where this check was supposed to be, but it certainly
doesn't belong here.
