We were getting build warnings about:
net/ipv4/igmp.c: In function ‘igmp_group_added’:
net/ipv4/igmp.c:1227:14: warning: unused variable ‘net’ [-Wunused-variable]
net/ipv4/igmp.c: In function ‘ip_mc_inc_group’:
net/ipv4/igmp.c:1319:14: warning: unused variable ‘net’ [-Wunused-variable]
net/ipv4/igmp.c: In function ‘ip_mc_init_dev’:
net/ipv4/igmp.c:1646:14: warning: unused variable ‘net’ [-Wunused-variable]
net/ipv4/igmp.c: In function ‘ip_mc_up’:
net/ipv4/igmp.c:1665:14: warning: unused variable ‘net’ [-Wunused-variable]
These variables are only used when CONFIG_IP_MULTICAST is defined. Mark
them as '__maybe_unused'.
