Subject: Re: [PATCH for kernel 3.19] Avoid that scsi_device_put() triggers a kernel warning

I don't like this.  The problem is that sd_shutdown shouldn't even try
to grab a reference to the scsi device, nevermind the HBA module.

So I'd say this need a two step fix:

 (1) stop trying to call try_module_get from sd_shutdown
 (2) properly propagate the try_module_get return value
