nfsd: don't destroy global nfs4_file table in per-net shutdown

Browse Source 
[ Upstream commit 4102db175b ]

The nfs4_file table is global, so shutting it down when a containerized
nfsd is shut down is wrong and can lead to double-frees. Tear down the
nfs4_file_rhltable in nfs4_state_shutdown instead of
nfs4_state_shutdown_net.

Fixes: d47b295e8d ("NFSD: Use rhashtable for managing nfs4_file objects")
