nfc: netlink: fix double device reference drop

The function nfc_put_device(dev) is called twice to drop the reference
to dev when there is no associated local llcp. Remove one of them to fix
the bug.

Fixes: 52feb444 ("NFC: Extend netlink interface for LTO, RW, and MIUX parameters support")
Fixes: d9b8d8e1 ("NFC: llcp: Service Name Lookup netlink interface")
