drm/msm/sde: Skip heavy autorefresh checks when it's not enabled
These heavy checks for seeing if autorefresh is enabled are unneeded when the autorefresh config is disabled. These checks are performed on every display commit and show up as using a significant amount of CPU time in perf top. Skip them when it's unnecessary in order to improve display rendering performance. Signed-off-by: Sultan Alsawaf <sultan@kerneltoast.com>
