Subject: utsns: fix !CONFIG_UTS_NS behavior
From: "Serge E. Hallyn" <serue@us.ibm.com>

When CONFIG_UTS_NS=n, clone(CLONE_NEWUTS) quietly refuses.  So correctly does
not unshare a new uts namespace, but also does not return -EINVAL.

Fix this to return -EINVAL so the caller knows his request was denied.
