byte count of FrameBuffer in AWAITING_CLOSE state is not subtracted from readBufferBytesAllocated

FrameBuffer.close() doesn't subtract the count for that in AWAITING_CLOSE state.

public void close() {
// if we're being closed due to an error, we might have allocated a
// buffer that we need to subtract for our memory accounting.
if (state_ == FrameBufferState.READING_FRAME || state_ == FrameBufferState.READ_FRAME_COMPLETE)

{ readBufferBytesAllocated.addAndGet(-buffer_.array().length); }

trans_.close();
if (eventHandler_ != null)

{ eventHandler_.deleteContext(context_, inProt_, outProt_); }

}
