When there is layout state on a filesystem that is being "unlocked" that is now revoked, which involves closing the nfsd_file and releasing the vfs lease. To avoid races, ->ls_file can now be accessed either: - under ->fi_lock for the state's sc_file or - under rcu_read_lock() if nfsd_file_get() is used. To support this, ->fence_client and nfsd4_cb_layout_fail() now take a second argument being the nfsd_file.
