scsi: fixup kernel warning during rmmod()
Calling rmmod() on a FC driver will results in warnings like WARNING: CPU: 60 PID: 14640 at fs/sysfs/group.c:237 device_del+0x54/0x240() sysfs group ffffffff81eff140 not found for kobject '3:0:0:3' The problem here is that during scsi_remove_target() we will iterate over all devices, but fail to remove any of those as the call to scsi_device_get() fails the check to module_is_live(). Hence the devices will not be removed at this point, but all intermediate structures like fc rport etc. will be. Later on during scsi_forget_host() the devices are removed for real, but the device parent is already removed and causes this warning.
