To remove a LUN safely for iSCSI multiple connections, each connection
must return I/O channel after checking completion of all tasks.
Open/close mechanism provides a way to register callback to do it.
Registered callback will be called after checking completion of
outstanding tasks.
Making the close LUN function public is necessary to support hot removal.
