[Intel-gfx] [PATCH] don't use the pin ioctl in KMS mode

[Jesse Barnes]

The only things we try to pin in KMS mode are the cursor objects and
front buffer, and those are taken care of by the kernel anyway, so we
shouldn't even bother trying to pin them (well, not entirely true,
XvMC tries to pin as well, but it needs work w/KMS anyway). Any
objections?
