nfsd4: BUG_ON(!is_spin_locked()) no good on UP kernels

Most frequent symptom was a BUG triggering in expire_client, with the server locking up shortly thereafter.

Introduced by 508dc6e110c6dbdc0bbe84298ccfe22de7538486 "nfsd41:
free_session/free_client must be called under the client_lock".

NFS: hard-code init_net for NFS callback transports

In case of destroying mount namespace on child reaper exit, nsproxy is zeroed to the point already. So, dereferencing of it is invalid.
This patch hard-code "init_net" for all network namespace references for NFS callback services. This will be fixed with proper NFS callback containerization.
