This patch removes some leftovers for commit

"[SCSI] zfcp: remove access control tables interface".

The "access denied" case for ports is gone, as well.
The corresponding flag was cleared, but never set.
So clean it up.

Sysfs flag is kept, though, for backward-compatibility.
Now it returns always 0.
