Pan Bian 1143496c96 nfc: netlink: fix double device reference drop 
[ Upstream commit 025ec40b81 ]

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: 52feb444a9 ("NFC: Extend netlink interface for LTO, RW, and MIUX parameters support")
Fixes: d9b8d8e19b ("NFC: llcp: Service Name Lookup netlink interface")
