1. Lower the poll timeout for the ofw console driver from hz / 50 to hz / 4.

Browse source 
This gives a bit of a sluggish console, but it prevents the console from
   getting stuck if we poll too fast, as well as other badness on certain
   machines.
2. Fix a test for != 0 that should have been > 0.
