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. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
