[SCSI] unify SCSI_IOCTL_SEND_COMMAND implementations
We currently have two implementations of this obsolete ioctl, one in the block layer and one in the scsi code. Both of them have drawbacks. This patch kills the scsi layer version after updating the block version with the missing bits: - argument checking - use scatterlist I/O - set number of retries based on the submitted command This is the last user of non-S/G I/O except for the gdth driver, so getting this in ASAP and through the scsi tree would be nie to kill the non-S/G I/O path. Jens, what do you think about adding a check for non-S/G I/O in the midlayer? Thanks to Or Gerlitz for testing this patch.
