Paolo Abeni 24b43c9964 infiniband: avoid dereferencing uninitialized dst on error path ... With commit eea40b8f62 ("infiniband: call ipv6 route lookup via the stub interface"), if the route lookup fails due to ipv6 being disabled, the dst variable is left untouched, and the following dst_release() may access uninitialized memory. Since ipv6_dst_lookup() always sets dst to NULL in case of lookup failure with ipv6 enabled, fix the above just returning the error code if the lookup fails.
