Tong Wu f303c26292 avcodec/vaapi_encode: move pic->input_surface initialization to encode_alloc 
When allocating the VAAPIEncodePicture, pic->input_surface can be
initialized right in the place. This movement simplifies the send_frame
logic and is the preparation for moving vaapi_encode_send_frame to the base layer.
