amd74xx/via82cxxx: check ide_config_drive_speed() return value

* Check ide_config_drive_speed() return value.

* While at also call ide_config_drive_speed() if the transfer mode is
  XFER_PIO_SLOW (this case happens iff the transfer mode has already been
  set on the device by ide-proc.c::set_xfer_rate()) and remove redundant
  setting of ->{init,current}_speed.

* Bump driver version.
