[PATCH] Bluetooth: SMP: Fix crash when receiving new connection when debug is enabled
From: Luiz Augusto von Dentz <luiz.dentz@gmail.com>

From: Luiz Augusto von Dentz <redacted>
When receiving a new connection pchan->conn won't be initialized so the
code cannot use bt_dev_dbg as the pointer to hci_dev won't be
accessible.
Fixes: 2e1614f7d61e4 ("Bluetooth: SMP: Convert BT_ERR/BT_DBG to bt_dev_err/bt_dev_dbg")
