netlabel: Fix some sparse warnings
Fix a few sparse warnings. One dealt with a RCU lock being held on error, another dealt with an improper type caused by a signed/unsigned mixup while the rest appeared to be caused by using rcu_dereference() in a list_for_each_entry_rcu() call. The latter probably isn't a big deal, but I derive a certain pleasure from knowing that the net/netlabel is nice and clean. Thanks to James Morris for pointing out the issues and demonstrating how to run sparse. Signed-off-by: Paul Moore <paul.moore@hp.com>
