context: reset VA context if VA surfaces set changed.
It is a requirement from VA-API specification that the VA context got from vaCreateContext(), for decoding purposes, binds the supplied set of VA surfaces. This means that if the set of VA surfaces is to be changed for the current decode session, then the VA context needs to be recreated with the new set of VA surfaces.
