[PATCH 9/15] ide-{floppy,tape,scsi}: fix register loading order when issuing packet command

[Bartlomiej Zolnierkiewicz]

Load IDE_BCOUNTL_REG before IDE_BCOUNTH_REG when issuing packet command.

It shouldn't affect anything (just a usual paranoia to separate changes
which change the way in which hardware is accessed from code cleanups).
