[PATCH] scsi: zfcp: move the position of put_device

[Qinglang Miao]

Have the `put_device()` call after `device_unregister()` in both
`zfcp_unit_remove()` and `zfcp_sysfs_port_remove_store()` to make
it more natural, for put_device() ought to be the last time we
touch the object in both functions.
