scsi: NCR5380: Use DRIVER_SENSE to indicate valid sense data

[ Upstream commit 070356513963be6196142acff56acc8359069fa1 ]

When sense data is valid, call set_driver_byte(cmd, DRIVER_SENSE).  Otherwise
some callers of scsi_execute() will ignore sense data.  Don't set DID_ERROR or
DID_RESET just because sense data is missing.
