ipv6: fix "'ioam6_if_id_max' defined but not used" warn 

When compiling without CONFIG_SYSCTL, this warning appears:

  net/ipv6/addrconf.c:99:12: error: 'ioam6_if_id_max' defined but not used [-Werror=unused-variable]
     99 | static u32 ioam6_if_id_max = U16_MAX;
        |            ^~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

Simply moving the declaration of this variable under ...

  #ifdef CONFIG_SYSCTL

... with other similar variables fixes the issue.

Fixes: 9ee11f0fff ("ipv6: ioam: Data plane support for Pre-allocated Trace")
