crypto: Fix hs_ntor MAC zero validation

A likely copy-pasta made its way through review which made the `rend_cell_auth`
never checked for all-zero.

This is not that problematic has the chances for SHA3 to generate a zeroed
buffer is close to impossible but defense in depth always.

Related to #41228
