New Revision: 218567
URL: http://svn.freebsd.org/changeset/base/218567

Log:
  Mfp4 CH=177255:
  
    Resort the CURVNET_SET* macros in the non-VNET_DEBUG case to match
    the call order of the VNET_DEBUG case.
  
    Add the VNET_ASSERT() to the non-VNET_DEBUG case as well so that
    INVARIANTS will still catch problems.
