[Piglit] [PATCH] dsa/xfb: make the buffer large enough.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This bug in the test was triggered by a fix to mesa, the test creates
a backing buffer smaller than the xfb range it requests then is surprised
when it gets returned a truncated value for the size.
