[PATCH 1/6] icside: fix ->speedproc to return on unsupported modes

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

icside_set_speed() happily accepts unsupported transfer modes which
results in drive->drive_data being set to the maximum value (480)
and drive->current_speed being set to the unsupported transfer mode.

Fix it.
