ide-floppy: pass packet command in rq->cmd
Make a redundant copy of the packet command bits into rq->cmd. Later, after all drivers have been converted, it'll be switched to use that in the common code instead of pc->c. There should be no functionality change resulting from this patch. Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
