knfsd: cache unregistration needn't return error
There's really nothing much the caller can do if cache unregistration fails. And indeed, all any caller does in this case is print an error and continue. So just return void and move the printk's inside cache_unregister. Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
