PATCH 1/1 semctl.2: Correct SEM_STAT_ANY description

From: Yang Xu <[email protected]>

Since kernel commit a280d6dc77eb
("ipc/sem: introduce semctl(SEM_STAT_ANY)"),
it only skips read access check when using SEM_STAT_ANY command. And it should use the semid_ds struct instead of seminfo struct. Fix this.
