This test is unnecessary. The function is not exported, and therefore
can only be called from vhost library. And all call sites are passing
a pointer to local data.
Adding extra parameter checks to internal functions bloats code
and creates lots of untestable paths. Coverity might even be
smart enough to detect these.
