scsi: iscsi: Ensure sysfs attributes are limited to PAGE_SIZE

Browse source

commit ec98ea7070 upstream.

As the iSCSI parameters are exported back through sysfs, it should be
enforcing that they never are more than PAGE_SIZE (which should be more
than enough) before accepting updates through netlink.

Change all iSCSI sysfs attributes to use sysfs_emit().
