net/ipv6: Fix gfp_flags arg to addrconf_prefix_route
Eric noticed that __ipv6_ifa_notify is called under rcu_read_lock, so
the gfp argument to addrconf_prefix_route can not be GFP_KERNEL.
While scrubbing other calls I noticed addrconf_addr_gen has one
place with GFP_ATOMIC that can be GFP_KERNEL.
Fixes: acb54e3cba404 ("net/ipv6: Add gfp_flags to route add functions")
