[1/1] usb: host: xhci: do not return error status for URB

[Peter Chen <hzpeterchen@gmail.com>]

Current XHCI implementation does not consider completion interrupt
for SETUP packet standalone, so it will show warning message
and return error status for URB. In fact, it can support it. In
this commit, we change warning message as debug message and set
status as zero for URB.

Support completion interrupt for SETUP packet is needed for USB EH2.0
SINGLE_STEP_SET_FEATURE Test.
