xhci: Treat not finding the event_seg on COMP_STOP the same as COMP_STOP_INVAL

When using a Renesas uPD720231 chipset usb-3 uas to sata bridge with a 120G
Crucial M500 ssd, model string: Crucial_ CT120M500SSD1, together with a
the integrated Intel xhci controller on a Haswell laptop:

00:14.0 USB controller [0c03]: Intel Corporation 8 Series USB xHCI HC [8086:9c31] (rev 04)

The following error gets logged to dmesg:

xhci error: Transfer event TRB DMA ptr not part of current TD

Treating COMP_STOP the same as COMP_STOP_INVAL when no event_seg gets found
fixes this.
