scsi: zfcp: Move the position of put_device()
Place the put_device() call after device_unregister() in both
zfcp_unit_remove() and zfcp_sysfs_port_remove_store() to make it more
natural. put_device() ought to be the last time we touch the object in both
functions.
Add comments after put_device() to make code clearer.
