avcodec/vvc/vvcdec: Do not submit frames without VVCFrameThread

Browse Source 
Such frames will crash when pthread functions are called on the NULL pointer

Fixes: member access within null pointer of type 'VVCFrameThread' (aka 'struct VVCFrameThread')
Fixes: 65160/clusterfuzz-testcase-minimized-ffmpeg_BSF_VVC_METADATA_fuzzer-4665241535119360 (partly)
Fixes: 65636/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_VVC_fuzzer-5394745824182272
