NTB: fix possible name leak in ntb_register_device()

mainline inclusion
from mainline-v6.9-rc1
commit aebfdfe39b9327a3077d0df8db3beb3160c9bdd0
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L9IV
CVE: CVE-2023-52652

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=aebfdfe39b9327a3077d0df8db3beb3160c9bdd0



--------------------------------

If device_register() fails in ntb_register_device(), the device name
allocated by dev_set_name() should be freed. As per the comment in
device_register(), callers should use put_device() to give up the
reference in the error path. So fix this by calling put_device() in the
error path so that the name can be freed in kobject_cleanup().

As a result of this, put_device() in the error path of
ntb_register_device() is removed and the actual error is returned.
