[PATCH] scsi: osd_uld: fix mismerge

A mismerge between two branches in linux-next reintroduced a warning that was
previously resolved:

drivers/scsi/osd/osd_uld.c: In function 'osd_probe':
drivers/scsi/osd/osd_uld.c:457:2: error: ignoring return value of 'scsi_device_get', declared with attribute warn_unused_result [-Werror=unused-result]

The original fix had more complex error unrolling, but as far as I
can tell, this simpler version is now sufficient.

Fixes: c02465fa13b6 ("scsi: osd_uld: Check scsi_device_get() return value")
Fixes: ac1ddc584e98 ("scsi: utilize new cdev_device_add helper function")
