[SCSI] raid_attrs: fix dependency problems
RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific checking code. This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.
