SurfaceView: Force surface disconnection before reuse.

Prior to N, if a client received the surfaceDestroyed callback
from their SurfaceView they could trust that the surface would not be
reused. Now that is not true in multiple scenarios. If a client fails
to shut down its EGL context then, we could end up in a situation where,
the client will never disconnect. Then when we reuse the same
underlying IGraphicBufferProducer for surfaceCreated next
the app will crash with a double connect error. There is no valid
use of the surface inbetween surfaceDestroyed and surfaceCreated,
so we just force the disconnection after surfaceDestroyed.
