Subject: [PATCH] RDMA/srpt: Add a newline when printing parameter 'srpt_service_guid' by sysfs

When I cat module parameter 'srpt_service_guid', it displays as follows.
It is better to add a newline for easy reading.

[root@...k-202 ~]# cat /sys/module/ib_srpt/parameters/srpt_service_guid
0x0205cdfffe8346b9[root@...k-202 ~]#
