Robert Watson 5ac3b03500 Properly return the error from mls_subject_privileged() in the ifnet
relabel check for MLS rather than returning 0 directly.

This problem didn't result in a vulnerability currently as the central
implementation of ifnet relabeling also checks for UNIX privilege, and
we currently don't guarantee containment for the root user in mac_mls,
but we should be using the MLS definition of privilege as well as the
UNIX definition in anticipation of supporting root containment at some
point.
