  Log:
  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.
