xf86/logind: fix missing call to vtenter if the platform device is not paused 

If there is one platform device, which is not paused nor resumed,
systemd_logind_vtenter() will never get called.
This break suspend/resume, and switching to VT on system with Nvidia
proprietary driver.
This is a regression introduced by f5bd039633

So now call systemd_logind_vtenter() if there are no paused
platform devices.

Closes: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1271
Fixes: f5bd0396 - xf86/logind: fix call systemd_logind_vtenter after receiving drm device resume
