usb: dwc3: Ignore late xferNotReady event to prevent halt timeout
During a device-initiated disconnect, the End Transfer command resets
the event filter, allowing a new xferNotReady event to be generated
before the controller is fully halted. Processing this late event
incorrectly triggers a Start Transfer, which prevents the controller
from halting and results in a DSTS.DEVCTLHLT bit polling timeout.
Ignore the late xferNotReady event if the controller is already in a
disconnected state.
