UPSTREAM: ipv6: addrconf_f6i_alloc - fix non-null pointer check to !IS_ERR()

Browse Source 
Fixes a stupid bug I recently introduced...
ip6_route_info_create() returns an ERR_PTR(err) and not a NULL on error.

Fixes: d55a2e374a ("net-ipv6: fix excessive RTF_ADDRCONF flag on ::1/128 local route (and others)'")
