[SCSI] convert SPI transport class to scsi_execute
This one's slightly more difficult. The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
