- Update display->vrows when fbset changes certain fields in var (such as
  color depth) but without changing the display resolution.  This might
  produce concommitant changes in other fields such as and especially
  var->yres_virtual.

- Clear the FBINFO_MISC_MODECHANGEUSER flag _before_ issuing a
  notifier_call_chain().  Clearing it after the notifier_call_chain() will
  cause fbcon to go into an infinite loop.

- Sanitized failure path of set_con2fb_map().
