LSM: fix documentation for the socket_getpeersec_dgram hook

Browse Source 
The socket_getpeersec_dgram hook was changed in the commit
"[AF_UNIX]: Kernel memory leak fix for af_unix datagram
getpeersec patch" (dc49c1f94e). The arguments @secdata
and @seclen were changed to @sock and @secid. This patch
updates the documentation accordingly.
