chinese email display problem

Bug description:
VM 7.19, but the code is the same in 8.0.X.
Received MIME email with part encoded text/plain, charset GB2312.
Running Emacs 23.0.92.4 in a plain text terminal window that understands utf-8.
Variable vm-mime-charset-converter-alist is set so that gb2312 is converted to utf-8.

When I display the email message, VM converts it to utf-8, which my terminal
program is set up to display.  I see the correct Chinese characters when I place a
(sit-for 5) at the beginning of vm-mime-charset-decode-region, but the buffer is later
messed up by this function.  I think the order of the COND tests is wrong.  The function
should do nothing if display of multiple fonts is impossible or the charset (utf-8) is
my VM MIME default face.  The following patch fixes the problem for me.
