[113/129] agp/intel: Promote warning about failure to setup flush to error.

[Greg KH]

2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>

commit df51e7aa2cf204e3a65657a1d60b96cfda133e9b upstream.

Make sure we always detect when we fail to correctly allocate the Isoch
Flush Page and print an error to warn the user about the likely memory
corruption that will result in invalid rendering or worse.
