[PATCH 7/8] drm/i915: Un-invert {i9xx,i965}_error_mask()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Make life a bit more straightforward by removing the bitwise
not from {i9xx,i965}_error_mask() and instead do it when feeding
the value to gen2_error_init(). Make life a bit easier I think.
