    Add an assertion to test_hs_cache.c to appease coverity.
    
    Coverity doesn't like to see a path where we test a pointer for
    NULL if we have already ready dereferenced the pointer on that
    path.  While in this case, the check is not needed, it's best not to
    remove checks from the unit tests IMO.  Instead, I'm adding an
    earlier check, so that coverity, when analyzing this function, will
    think that we have always checked the pointer before dereferencing
    it.
    
    Closes ticket 30180; CID 1444641.
