[patch 4/6] zfcp: Remove SCSI devices when removing complete adapter

[swen]

From: Christof Schmitt <christof.schmitt@xxxxxxxxxx>

The common I/O layer can call remove a handler to inform zfcp
that a device disappeared. The handler zfcp_ccw_remove then
removes all unit, port and the adapter data structures. Removing
the units requires that the SCSI devices are removed first.
