Remove unnecessary code rom be_lo_put()

[Yugo NAGATA]

Hi,

I noticed that a permission check is performed in be_lo_put()
just after returning inv_open(), but teh permission should be
already checked in inv_open(), so I think we can remove this
part of codes. I attached a patch for this fix.

Regards,
Yugo Nagata
