xhci: print warning when HCE was set
When HCE(Host Controller Error) is set, it means that the xhci hardware
controller has an error at this time, but the current xhci driver
software does not log this event.
By adding an HCE event detection in the xhci interrupt processing
interface, a warning log is output to the system, which is convenient
for system device status tracking.
