i965/skl/gt4: Fix URB programming restriction.

The comment in the code details the restriction. Thanks to Ken for having a very
helpful conversation with me, and spotting the blurb in the link I sent him :P.

There are still stability problems for me on GT4, but this definitely helps with
some of the failures.

v2: Comment fixes
