ipv4: rcu cleanup in ip_ra_control()
Remove one sparse warning : net/ipv4/ip_sockglue.c:328:22: warning: incorrect type in assignment (different address spaces) net/ipv4/ip_sockglue.c:328:22: expected struct ip_ra_chain [noderef] <asn:4>*next net/ipv4/ip_sockglue.c:328:22: got struct ip_ra_chain *[assigned] ra And replace one rcu_assign_ptr() by RCU_INIT_POINTER() where applicable.
