USB: ehci: paranoia, reject large control transfers
Some EHCI fault paths with large control transfers aren't coded. Avoid problems by rejecting transfers that may need two qTDs (16+ KB). This is mostly paranoia; even 4 KB transfers are rare, and most HCDs use lower limits (so it's unlikely anyone would ever try such a thing).
