skd: Make it easier for static analyzers to analyze skd_free_disk()
Although it is easy to see that skdev->disk != NULL if skdev->queue
!= NULL, add a test for skdev->disk to avoid that smatch reports the
following warning:
drivers/block/skd_main.c:3080 skd_free_disk()
error: we previously assumed 'disk' could be null (see line 3074)
