scsi: fcoe: Fix possible name leak when device_register() fails
[ Upstream commit 47b6a122c7b69a876c7ee2fc064a26b09627de9d ]
If device_register() returns an error, the name allocated by dev_set_name()
needs to be freed. As the comment of device_register() says, one should use
put_device() to give up the reference in the error path. Fix this by
calling put_device(), then the name can be freed in kobject_cleanup().
The 'fcf' is freed in fcoe_fcf_device_release(), so the kfree() in the
error path can be removed.
The 'ctlr' is freed in fcoe_ctlr_device_release(), so don't use the error
label, just return NULL after calling put_device().
