Allocate new native handle to store sidebandStream

When we get sidebandStream from TvInput, we only store the address of
native handle, the address point to native_handle_t in _hidl_replay.
After openStream is finished, the _hidl_replay will be freed
automatically, therefore we will use the freed memory in
setSidebandStrem, It will cause the writeNativeHandle fail in
setSidebandStrem.
