syndaemon: don't compare against a null-property. (#37459)

Browse Source 
synaptics_property is not set, touchpad_off_prop is the property we need to
check against.

False check for (nprops != 0) instead of (nprops < 0) would result in
syndaemon always reporting a touchpad device, even if none are present.
