hantro: Move hantro_enc_buf_finish to JPEG codec_ops.done
hantro_enc_buf_finish is used only for JPEG, and so should
be moved to JPEG codec_ops.done.
This cleanup is also taking care of addressing
a subtle issue: checking the non-NULL bounce buffer
using ctx->jpeg_enc, which is a member of a union is
confusing and error-prone.
Note that the issue is currently innocuous because an
encoder context only supports JPEG.
The codec_ops.done has an argument that codec-specific code
shouldn't need, so drop that as well.
