Geoff Levand beaa4867ee fbcon: fix workqueue shutdown 
Add a call to cancel_work_sync() in fbcon_exit() to cancel any pending
work in the fbcon workqueue.

The current implementation of fbcon_exit() sets the fbcon workqueue
function info->queue.func to NULL, but does not assure that there is no
work pending when it does so.  On occasion, depending on system timing,
there will still be pending work in the queue when fbcon_exit() is
called.  This results in a null pointer deference when run_workqueue()
tries to call the queue's work function.

Fixes errors on shutdown similar to these:

  Console: switching to colour dummy device 80x25
  Unable to handle kernel paging request for data at address 0x00000000
