nfsd4: remove state lock from nfsd4_load_reboot_recovery_data
That function is only called under nfsd_mutex: we know that because the
only caller is nfsd_svc, via
nfsd_svc
nfsd_startup
nfs4_state_start
nfsd4_client_tracking_init
client_tracking_ops->init == nfsd4_load_reboot_recovery_data
The shared state accessed here includes:
- user_recovery_dirname: used here, modified only by
nfs4_reset_recoverydir, which can be verified to only be
called under nfsd_mutex.
- filesystem state, protected by i_mutex (handwaving slightly
here)
- rec_file, reclaim_str_hashtbl, reclaim_str_hashtbl_size: other
than here, used only from code called from nfsd or laundromat
threads, both of which should be started only after this runs
(see nfsd_svc) and stopped before this could run again (see
nfsd_shutdown, called from nfsd_last_thread).
