Remove ctx->pending_cx_data

Code analysis shows:
1. ctx->pending_cx_data is only set to two values: NULL or ctx->cx_data.
2. ctx->pending_cx_data is NULL whenever ctx->pending_cx_data_sz is
zero, and ctx->pending_cx_data is non-NULL whenever
ctx->pending_cx_data_sz is nonzero.

Therefore, we can delete ctx->pending_cx_data and replace it with
ctx->cx_data. To check if there is pending data (invisible frames) in
ctx->cx_data, we can check if ctx->pending_cx_data_sz is nonzero.
