Subject: scsi: ignore errors from scsi_dh_add_device()

From: Hannes Reinecke <[email protected]>

commit 221255aee67ec1c752001080aafec0c4e9390d95 upstream.

device handler initialisation might fail due to a number of reasons. But as device_handlers are optional this shouldn't cause us to disable the device entirely.
So just ignore errors from scsi_dh_add_device().
