Replace kernel USB speed numbers with xHCI protocol IDs expected by HW. They are numerically equal up to high speed, but instead of SuperSpeed we were querying SuperSpeed+. Gen1 hardware rejects such commands with TRB Error, which resulted in zero available bandwidth being shown. While at that, report failures properly. No attempt made at "tunneling" all possible comp codes through errno, debugfs users may inspect the result through event-ring/trbs.
