[PATCH] generic_serial: fix decoding of baud rate

Commit d720bc4b8fc5d6d179ef094908d4fbb5e436ffad partially removed a
private implementation of baud speed decoding.  However it doesn't seem
to be complete: after the speed is decoded, it is still being used as an
index to a local speed table (array overrun, no doubt).

This was found by Graham Murray who noticed it caused a 2.6.19 regression
with the SX driver: https://bugs.gentoo.org/170554
