When CONFIG_IPV6 is not set, then the linking of the lan966x driver
fails with the following error:
drivers/net/ethernet/microchip/lan966x/lan966x_main.c:444: undefined
reference to `ipv6_mc_check_mld'
The fix consists in adding a check also for IS_ENABLED(CONFIG_IPV6)
Fixes: 47aeea0d57e80c ("net: lan966x: Implement the callback SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED")

v1->v2:
- use IS_ENABLED(CONFIG_IPV6) instead of #ifdef
