[PATCH] SGI-XPC: Delete unnecessary checks before unregister_sysctl_table()
From: SF Markus Elfring

The unregister_sysctl_table() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
