s390/compat,uid16: use current_cred()
86a264ab "CRED: Wrap current->cred and a few other accessors" converted all uses of current->cred into current_cred() but left s390 alone. So let's convert s390 finally as well, only five years later. This way we also get rid of a sparse warning which complains about a possible invalid rcu dereference which however is a false positive.
