[NET] NETNS: Omit namespace comparision without CONFIG_NET_NS.
Introduce an inline net_eq() to compare two namespaces. Without CONFIG_NET_NS, since no namespace other than &init_net exists, it is always 1. We do not need to convert 1) inline vs inline and 2) inline vs &init_net comparisons. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
