knfsd: allow cache_register to return error on failure
Newer server features such as nfsv4 and gss depend on proc to work, so a
failure to initialize the proc files they need should be treated as
fatal.
Thanks to Andrew Morton for style fix and compile fix in case where
CONFIG_NFSD_V4 is undefined.
