Fix unexpected FrameEvents on BufferQueue reconnect

Helps reduce the number of ALOGE's being hit
when switching between apps.

* Notify Layer when the Producer disconnects.
* Avoid sending event deltas from a previous connection.
* Avoid releasing a frame more than once.

Test: adb shell /data/nativetest/libgui_test/libgui_test
    --gtest_filter=*GetFrameTimestamps*
