From: Arnd Bergmann <arnd@arndb.de>

ioam6_if_id_max is defined globally but used only when
CONFIG_SYSCTL is enabled:

net/ipv6/addrconf.c:99:12: error: 'ioam6_if_id_max' defined but not used [-Werror=unused-variable]

Move the variable definition closer to the usage inside of the
same #ifdef.

Fixes: 9ee11f0fff20 ("ipv6: ioam: Data plane support for Pre-allocated Trace")
