nfsd: simplify NFSv4 state init and shutdown
This patch moves nfsd_startup_generic() and nfsd_shutdown_generic()
calls to nfsd_startup_net() and nfsd_shutdown_net() respectively, which
allows us to call nfsd_startup_net() instead of nfsd_startup() and makes
the code look clearer. It also modifies nfsd_svc() and nfsd_shutdown()
to check nn->nfsd_net_up instead of global nfsd_up. The latter is now
used only for generic resources shutdown and is currently useless. It
will replaced by NFSd users counter later in this series.
