2a0788dc9b x86: Use clflushopt in drm_clflush_virt_range

If clflushopt is available on the system, we use it instead of clflush
in drm_clflush_virt_range.  There were two calls to clflush in this
function, but only one was changed to clflushopt.  This patch changes
the other clflush call to clflushopt.
