[Intel-gfx] i965: aperture fixes 59b2c2adb cause lockups in foobillard at startup

[Keith Packard]

While doing a bunch of irq work, I was testing random programs against
mesa master and found that foobillard (debian unstable version) was
locking up on my GM45 laptop. I bisected and found that this patch was
causing the trouble. I haven't looked to try and figure out what's going
on.

    i965: Fix check_aperture calls to cover everything needed for the prim at once.
    
    Previously, since my check_aperture API change, we would check each piece of
    state against the batchbuffer individually, but not all the state against the
    batchbuffer at once.  In addition to not being terribly useful in assuring
    success, it probably also increased CPU load by calling check_aperture many
    times per primitive.
