[PATCH v2 08/12] Bluetooth: btusb: Simplify btusb_shutdown_qca() by using __hci_reset_sync()

[Zijun Hu]

btusb_shutdown_qca() open-codes a synchronous raw HCI reset that is
functionally equivalent to the newly added __hci_reset_sync().

Replace it with __hci_reset_sync() and return its result directly.
