Fix the problem that mDamageGenerationId is a random value

1. mDamageGenerationId is a random value when initialized. When this random value happens to be equal to info.damageGenerationId, the dirty range will reach the maximum DIRTY_MAX.
2. When info.damageGenerationId is equal to 0, which is when the first frame of the APP is drawn, there is no need to reach the maximum DIRTY_MAX in the dirty range.
