netns: move {inc,dec}_net_namespaces into #ifdef
With the newly enforced limit on the number of namespaces,
we get a build warning if CONFIG_NETNS is disabled:
net/core/net_namespace.c:273:13: error: 'dec_net_namespaces' defined but not used [-Werror=unused-function]
net/core/net_namespace.c:268:24: error: 'inc_net_namespaces' defined but not used [-Werror=unused-function]
This moves the two added functions inside the #ifdef that guards
their callers.
Fixes: 703286608a22 ("netns: Add a limit on the number of net namespaces")
