hevc/sei: return INVALIDDATA when a referenced SPS is not available

Browse Source 
The code previously returned ENOMEM, despite this not being an
allocation problem, but rather a bitstream problem referring to data not
currently available.

Fixes playback of such streams, as it allows further processing of NAL
units after skipping the broken SEI NAL.
