USB: ftdi_sio: fix TIOCSSERIAL baud_base handling Return EINVAL if new baud_base does not match the current one. The baud_base is device specific and can not be changed. This restores the old (pre-2005) behaviour which was changed due to a misunderstanding regarding this fact (see https://lkml.org/lkml/2005/1/20/84).
