Subject: net/ipv6/route.c: work around gcc-4.4.4 anon union initializer issue

gcc-4.4.4 has problems with initializers of anonymous union fields.

net/ipv6/route.c: In function 'rt6_sync_up':
net/ipv6/route.c:3586: error: unknown field 'nh_flags' specified in initializer
net/ipv6/route.c:3586: warning: missing braces around initializer
net/ipv6/route.c:3586: warning: (near initialization for 'arg.<anonymous>')
net/ipv6/route.c: In function 'rt6_sync_down_dev':
net/ipv6/route.c:3695: error: unknown field 'event' specified in initializer
net/ipv6/route.c:3695: warning: missing braces around initializer
net/ipv6/route.c:3695: warning: (near initialization for 'arg.<anonymous>')
