drm/i915/gvt: Do not allocate initial ring scan buffer Theoretically, the largest bulk of commands in the ring buffer of an engine might be the first submission, which usually contains a lot of commands to initialize the HW. After removing the initial allocation of the ring scan buffer and let krealloc() do everything we need, we still have a big chance to get the buffer of suitable size in the first submission. Tested on my SKL NUC. Signed-off-by: Zhi Wang <zhi.a.wang@intel.com>
