Subject: RDMA/srpt: Add a newline when printing parameter 'srpt_service_guid'
 by sysfs
Patch-mainline: v5.8-rc1
Git-commit: a8f5c1f1a5c80e5a4bde5eaa1de645d72c562da6
References: jsc#SLE-15176

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

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