Subject: [PATCH 6.0 334/862] Bluetooth: hci_sync: Fix not indicating power state

From: Luiz Augusto von Dentz <luiz.von.dentz@...el.com>

[ Upstream commit 6abf0dae8c3c927f54e62c46faf8aba580ba0d04 ]

When setting power state using legacy/non-mgmt API
(e.g hcitool hci0 up) the likes of mgmt_set_powered_complete won't be
called causing clients of the MGMT API to not be notified of the change
of the state.

Fixes: cf75ad8b41d2 ("Bluetooth: hci_sync: Convert MGMT_SET_POWERED")
