[GIT PULL 5/9] hw/display/virtio-gpu: drop redundant node->value NULL checks

QAPI-generated list visitors guarantee that node->value is never NULL:
the input visitor allocates it via g_malloc0() in visit_start_struct(),
and on failure the entire list parse is aborted and freed.
Remove the unnecessary NULL checks from both callsites iterating
g->conf.outputs.
Resolves: Coverity CID 1664272
Fixes: 8dc8449a678f ("hw/display/virtio-gpu: Avoid leaking migration blocker")
