Subject: [PATCH 2/2] sunrpc: add missing newline when printing parameter 'auth_hashtable_size' by sysfs

When I cat parameter
'/sys/module/sunrpc/parameters/auth_hashtable_size', it displays as
follows. It is better to add a newline for easy reading.

[root@...k-202 ~]# cat /sys/module/sunrpc/parameters/auth_hashtable_size
16[root@...k-202 ~]#
