'mod' is not used when !CONFIG_MODULES. Mark as __maybe_unused to
fix the following warning:

kernel/static_call.c: In function =E2=80=98__static_call_update=E2=80=99:
kernel/static_call.c:153:18: warning: unused variable =E2=80=98mod=E2=80=99=
 [-Wunused-variable]
  153 |   struct module *mod =3D site_mod->mod;
      |                  ^~~
