Luiz Augusto von Dentz 13e17a18a4 Bluetooth: L2CAP: Fix l2cap_global_chan_by_psm regression 
commit 332f1795ca202489c665a75e62e18ff6284de077 upstream.

The patch d0be8347c623: "Bluetooth: L2CAP: Fix use-after-free caused
by l2cap_chan_put" from Jul 21, 2022, leads to the following Smatch
static checker warning:

        net/bluetooth/l2cap_core.c:1977 l2cap_global_chan_by_psm()
        error: we previously assumed 'c' could be null (see line 1996)
