avcodec/rkmppdec: Fix double-free on error

After having created the AVBuffer that is put into frame->buf[0],
ownership of several objects (namely an AVDRMFrameDescriptor,
an MppFrame and some AVBufferRefs framecontextref and decoder_ref)
has passed to the AVBuffer and therefore to the frame.
Yet it has nevertheless been freed manually on error
afterwards, which would lead to a double-free as soon
as the AVFrame is unreferenced.
