Subject: [PATCH][next] media: pci: cx18-av-vbi: Replace one-element array
 with flexible-array member

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element arrays with flexible-array
members in struct vbi_anc_data.

This results in no differences in binary output.
