svn commit: r270272 - head/sys/dev/vt

Log:
  vt(4): If the cursor is globally disabled, don't mark its position as dirty
  
  This avoids unnecessary redraw. In particular, during boot, where the
  cursor is disabled and its fake position is [0;0], this triggered a
  refresh of the whole screen each time vt_flush() is called.
