nspawn: drop unnecessary wrapper functions

The naming was confused: suffix 'p' means that the function takes a pointer to
the type that the wrapped function takes. (E.g., a char**, for a wrapped function
taking a char*.)  But DEFINE_TRIVIAL_DESTRUCTOR() just changes the return type.

Also add one more assert for consistency.
