nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_net
Bugzilla: https://bugzilla.redhat.com/2215429
This patch fixes a regression that crept into upstream kernels and 9.3 with an earlier backport. Since the procfiles are available when nfsd isn't running, we also need to make sure that the percpu counters are always initialized.
