patch: xhci: return error if configure ep fails

[Takahiro HAYASHI <t.hash425%gmail.com@localhost>]

Hello,

This patch makes xhci_open return error code
if xhci_configure_endpoint fails, then, makes umass
comfortable if CONFIGURE_EP fails with TRB_ERROR_PARAMETER
when 3.0 usb drive is connected and umass tries to open
bulk-in/out endpoints.
I have no idea why configure endpoint fails on only my
uPD720200, even though it works on Etron and BayTrail.
