2a0788dc9bc4 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.
