patch 9.1.1765: f_isnan() and f_isinf() do not correctly initialize rettv type

Browse Source 
Problem:  f_isnan() and f_isinf() do not correctly initialize rettv type
Solution: Initialize them with type: VAR_NUMBER and value 0 (Damien Lejay).

Both builtins wrote only rettv->vval.v_number and relied on call_func()
initialising rettv->v_type to VAR_NUMBER.  Explicitly set

    rettv->v_type = VAR_NUMBER;
    rettv->vval.v_number = 0;

at function entry to avoid undefined behaviour and make the return type
self-contained.

closes: #18307
