Subject[PATCH][next] nfsd: 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 a one-element array
with a flexible-arrayº member in struct vbi_anc_data and refactor
the rest of the code, accordingly.

This results in no differences in binary output.
