Bluetooth: Fix issue with USB suspend in btusb driver
commit 85560c4a828ec9c8573840c9b66487b6ae584768 upstream.
Suspend could fail for some platforms because
btusb_suspend==> btusb_stop_traffic ==> usb_kill_anchored_urbs.
When btusb_bulk_complete returns before system suspend and resubmits
an URB, the system cannot enter suspend state.
