ovs.tmac: Fix troff warning in versions above groff-1.23.
Browse files Browse the repository at this point in the history 
When the compilation dependency is groff-1.23, the following message is
displayed in the compilation log, and the compilation fails:

  troff:vswitchd/ovs-vswitchd.8:1298: warning: cannot select font 'CW'
  make[1]: *** [Makefile:6761: manpage-check] Error 1

CW font was removed and and now groff warns about non-existent font:
 https://git.savannah.gnu.org/cgit/groff.git/commit/?id=d75ea8b2e283e37bd560e821fa4597065f36725f)

Fix that by replacing CW with CR.  CW supposed to be an alias of CR
anyway.
