vulkan_h264: check if slices_buf exists on end_frame
The issue is that while decode_slice is guaranteed to never get called without start_frame, end_frame is not. Moreover, it is not guaranteed it won't be called twice. On a badly-broken sample, this is what happens, which leads to a segfault, as vp->slices_buf doesn't exist, as it has been handed off for decoding already and isn't owned by the frame. Return an error as it's indicative that it's a corrupt stream rather than just missing any slices. Prevents a segfault.
