[PATCH nf-next v2 3/3] selftests: netfilter: fix typo "adress" in comment

misspelling list in scripts/spelling.txt. Only touches comments, no code
changes.

Notes:
    v2: designate the patch to nf-next and use a subject prefix naming the
    component, as maintainer-netdev.rst asks; v1 went out with a bare
    [PATCH] and a "net:" prefix. Rebased onto nf-next, diff unchanged.
    
    v1: https://lore.kernel.org/all/20260907064239.39910-1-hemanth.selam@gmail.com/ (local)
