scsi_sysfs: call 'device_add' after attaching device handler
'device_add' will be evaluating the 'is_visible' callback when creating the sysfs attributes. As by this time the device handler has not been attached the 'access_state' attribute will never be visible. This patch moves the code around so that the device handler is present by the time 'is_visible' is evaluated to correctly display the 'access_state' attribute.
