[SCSI] sd: remove command-size switching code
This patch (as1138) removes from sd.c some old code for switching from 10-byte commands to 6-byte commands. This code is redundant -- the switching for READ and WRITE is already handled in scsi_io_completion() and the switching for MODE SENSE is already handled in scsi_mode_sense(). (There is no comparable switch for MODE SELECT, but I doubt one is needed.) Furthermore the other handlers do a better job; they check for appropriate ASC and ASCQ values before blindly switching the size. The code in sd.c is known to cause problems with some devices by switching when it shouldn't.
