Revert "drm/i915: Fix races on fbdev"
This reverts commit a7442b93cf32c1e1ddb721a26cd1f92302e2a222.
With the patch applied SNB, IVB and ILK are experiencing hard machine
hangs. Original patch was to fix "just" kernel panics so it's not a good
trade-off.
Proper fix for the panic is on the way, lets revert until then.
