NFC: fix resource leak when target index is invalid
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")
