blkcg: fix gendisk reference leak in blkg_conf_prep()

[ Upstream commit 5f6c2d2b7dbb541c1e922538c49fa04c494ae3d7 ]

When a blkcg configuration is targeted to a partition rather than a
whole device, blkg_conf_prep fails with -EINVAL; unfortunately, it
forgets to put the gendisk ref in that case.  Fix it.
