Not remove surface when resource_id is 0

This is a workaround to solve the issue of black display
Observation is when Surfaceflinger falls back to guest composition,
host receives set scanout 0 0, and then set scanout 0 <some valid resid>.
The first 0 0 removes the surface, the second creates a new surface
with id++, which will be more than 0 and be ignored in vnc or webrtc

Test: launch_avd, switch between apps
