[Intel-gfx] [PATCH] intel: Add a missing VG_CLEAR.

[Eric Anholt]

This fixes the last false positive from libdrm for valgrind glxgears
for me.

I'm slightly nervous about removing memsets in favor of VG_CLEAR, in
case there are pad fields that might become important later.  But the
only one I could think of that this ought to be the case for was
execbuf, and that explicitly initializes the pad fields.  So Chris's
patch series is:

though it would be nice if we could teach upstream valgrind about our
ioctl parameters instead of just overriding all over this code, so
that other direct uses of our ioctls in X and Mesa didn't cause
valgrind spew either.
