drm: Missed clflushopt in drm_clflush_virt_range
With this commit:

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.
