Subject: [PATCH] Don't disable user session freezing if nvidia module isn't
 loaded

nvidia-utils from Arch ships a blanket rule that disables user session freezing on suspend. While this might be necessary on NVIDIA hardware, it's actively warned against by systemd and hence should not be set for everyone else.
