[PATCH 5.10 133/142] NFC: fix resource leak when target index is invalid

[Greg Kroah-Hartman]

From: Pan Bian <bianpan2016@xxxxxxx>

commit 3a30537cee233fb7da302491b28c832247d89bbe upstream.

Goto to the label put_dev instead of the label error to fix potential
resource leak on path that the target index is invalid.

Fixes: c4fbb6515a4d ("NFC: The core part should generate the target index")
