Subject: [PATCH 5.15 293/846] Bluetooth: hci_qca: Stop IBS timer during BT OFF

From: Panicker Harish <quic_pharish@...cinc.com>

[ Upstream commit df1e5c51492fd93ffc293acdcc6f00698d19fedc ]

The IBS timers are not stopped properly once BT OFF is triggered.
we could see IBS commands being sent along with version command,
so stopped IBS timers while Bluetooth is off.
