Subject: xhci dmesg flood on short packet

I see a continuous flood of below messages on plugging in/using my USB 
token. (The comp code wasn't in the original message - I added it.) From 
what I can tell the device continues to work as expected.

Should the warning be disabled for COMP_SHORT_TX like it is for COMP_STOP 
and COMP_STOP_INVAL?
