nfsd: make delegations shutdown network namespace aware
NFSv4 delegations are stored in global list. But they are nfs4_client dependent, which is network namespace aware already. State shutdown and laundromat are done per network namespace as well. So, delegations unhash have to be done in network namespace context. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
