security: fix documentation for the socket_getpeersec_dgram hook

From: Denis Efremov <[email protected]>

The socket_getpeersec_dgram hook was changed in the commit "[AF_UNIX]: Kernel memory leak fix for af_unix datagram getpeersec patch" (dc49c1f94e34). The arguments @secdata and @seclen were changed to @sock and @secid. This patch updates the documentation accordingly.
