[PATCH 02/18] scsi: ignore errors from scsi_dh_add_device()

[Hannes Reinecke <hare@suse.de>]

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().
