[PATCH] Bluetooth: l2cap: Don't double set the HCI_CONN_MGMT_CONNECTED bit

[PATCH] Bluetooth: l2cap: Don't double set the HCI_CONN_MGMT_CONNECTED bit

[Archie Pusaka]

From: Archie Pusaka <apusaka@chromium.org>

The bit is set and tested inside mgmt_device_connected(), therefore we
must not set it just outside the function.

Fixes: eeda1bf97bb5 ("Bluetooth: hci_event: Fix not indicating new connection for BIG Sync")
