[dvipdfmx] Font format is determined as OFM for TFM fonts

[Igor Liferenko]

Hi,

The following code on lines 887--890 of dvipdfm-x/tfm.c must be removed

 else if ((file_name =
               kpse_find_file(tfm_name, kpse_ofm_format, 0)) != NULL) {
     format = OFM_FORMAT;
   }

Firstly, this code is not necessary anyway, because OFM file is
already searched first.
And secondly, this code causes a bug:
if a tfm-file is found in OFMFONTS path, then
font type is determined as OFM_FORMAT.
So, ofm_open() is called for this tfm-file. This produces an error.

I think the person who wrote this code blindly copied it from what is now
between #if 0 ... #endif on lines 862--868 of dvipdfm-x/tfm.c
This code has this call:

     kpse_find_file(tfm_name, kpse_ofm_format, 0)

which is wrong: instead of tfm_name there should be ofm_name.

Best,
Igor
