[PATCH] drivers/char/specialix.c: fix the baud conversion

Correct the following bugs introduced by commit
67cc0161:

- remove one remaining and now incorrect baud_table[] usage
- "baud +=" is no longer correct

The former bug was spotted by the Coverity checker.

Rolf Eike Beer spotted a bug in the initial version of my patch.
