6.10-stable review patch. If anyone has any objections, please let me know.

From: Douglas Anderson <dianders@xxxxxxxxxxxx>
[ Upstream commit 8ae22de9d2eae3c432de64bf2b3a5a69cf1d1124 ]
On systems in the field, we are seeing this sometimes in the kernel logs:
Bluetooth: qca_controller_memdump() hci0: hci_devcd_init Return:-95
This means that _something_ decided that it wanted to get a memdump
but then hci_devcd_init() returned -EOPNOTSUPP (AKA -95).
The cleanup code in qca_controller_memdump() when we get back an error
from hci_devcd_init() undoes most things but forgets to clear
QCA_IBS_DISABLED. One side effect of this is that, during the next
suspend, qca_suspend() will always get a timeout.
Let's fix it so that we clear the bit.
