zfcp host adapter fixes:
 - Reuse freed scsi_ids and scsi_luns for mappings.
 - Order list of ports/units by assigned scsi_id/scsi_lun.
 - Don't update max_id/max_lun in scsi_host anymore.
 - Get rid of all magics.
 - Add owner field to ccw_driver structure.
 - Avoid deadlock on bus->subsys.rwsem.
 - Use a macro for all scsi device sysfs attributes.
 - Change proc_name from "dummy" to "zfcp".
 - Don't wait for scsi_add_device to complete while holding a semaphore.
 - Cleanup include files in zfcp_aux.c & zfcp_def.h.
 - Get rid of zfcp_erp_fsf_req_handler.
 - Proper link up/down handling.
 - Avoid possible NULL pointer dereference in zfcp_erp_schedule_work.
 - Remove module_exit function. Without an external release function for
   the zfcp_port/zfcp_unit objects module unloading is racy.
