This is the large change to switch from using the data in zfcp_unit to zfcp_scsi_dev. Keeping everything working requires doing the switch in one piece. To ensure that no code keeps using the data in zfcp_unit, this patch also removes the data from zfcp_unit that is now being replaced with zfcp_scsi_dev. For zfcp, the scsi_device together with zfcp_scsi_dev exist from the call of slave_alloc to the call of slave_destroy. The data in zfcp_scsi_dev is initialized in zfcp_scsi_slave_alloc and the LUN is opened; the final shutdown for the LUN is run from slave_destroy. Where the scsi_device or zfcp_scsi_dev is needed, the pointer to the scsi_device is passed as function argument and inside the function converted to the pointer to zfcp_scsi_dev; this avoids back and forth conversion betweeen scsi_device and zfcp_scsi_dev. While changing the function arguments from zfcp_unit to scsi_device, the functions names are renamed form "unit" to "lun". This is to have a seperation between zfcp_scsi_dev/LUN and the zfcp_unit; only code referring to the remaining configuration information in zfcp_unit struct uses "unit".
