kernel: Bluetooth: hci_sync: Set HCI_CMD_DRAIN_WORKQUEUE during device close

A flaw was found in the Bluetooth hcisync component of the Linux kernel. When the hcidevclosesync function is called during a device reset, the system may experience queuing timeouts. This occurs because the HCICMDDRAINWORKQUEUE flag is not properly set, which can lead to system instability or a...
