[SCSI] fix intermittent oops in scsi_bus_uevent

This causes both the scsi_device and scsi_target to fire scsi_bus_uevents. However, the actualy scsi_bus_uevent() call assumes blindly that it's a struct scsi_device. Check for this and return immediately if it isn't. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
