disp: msm: sde: move qsync validation to encoder atomic check

Browse Source 
In connector atomic check, seamless vrr cannot be
determined since mode doesn't get populated by that time.
This change moves qsync validation from connector to encoder
atomic check to verify & handle modeset concurrencies.
