[SCSI] scsi_transport.h should include scsi_device.h

scsi_transport.h defines the inline function scsi_transport_device_data() that
dereferences a pointer of "struct scsi_device *".  Since the struct is not
known by the header this might break compilation.

Include scsi/scsi_device.h to not rely on users doing the correct magic
include order.
