avcodec/vaapi_encode: Use RefStruct pool API, stop abusing AVBuffer API

Up until now, the VAAPI encoder uses fake data with the
AVBuffer-API: The data pointer does not point to real memory,
but is instead just a VABufferID converted to a pointer.
This has probably been copied from the VAAPI-hwcontext-API
(which presumably does it to avoid allocations).

This commit changes this without causing additional allocations
by switching to the RefStruct-pool API. This also fixes an
unchecked av_buffer_ref().
