vulkan_decode: reject decoding of frames with no slices

Browse Source 
As per the spec:
VUID-VkVideoDecodeH264PictureInfoKHR-sliceCount-arraylength
sliceCount must be greater than 0

VUID-VkVideoDecodeH265PictureInfoKHR-sliceSegmentCount-arraylength
sliceSegmentCount must be greater than 0

This particularly happens with seeking in field-coded H264.
