Subject: [PATCH] Bluetooth: 6LoWPAN: add missing hci_dev_put() in get_l2cap_conn()

Git-commit: 747da1308bdd5021409974f9180f0d8ece53d142

Patch-mainline: v6.1

References: git-fixes

hci_get_route() takes reference, we should use hci_dev_put() to release

it when not need anymore.

Fixes: 6b8d4a6a0314 ("Bluetooth: 6LoWPAN: Use connected oriented channel instead of fixed one")
