uio: fix incorrect memory leak cleanup
[ Upstream commit 0d83539092ddb1ab79b4d65bccb866bf07ea2ccd ]
Commit 75f0aef6220d ("uio: fix memory leak") has fixed up some
memory leaks during the failure paths of the addition of uio
attributes, but still is not correct entirely. A kobject_uevent()
failure still needs a kobject_put() and the kobject container
structure allocation failure before the kobject_init() doesn't
need a kobject_put(). Fix this properly.
Fixes: 75f0aef6220d ("uio: fix memory leak")
