USB: ehci: qh/qtd cleanup comments
Provide better comments about qh_completions() and QTD handling.
That code can be *VERY* confusing, since it's evolved over a few
years to cope with both hardware races and silicon quirks.
Remove two unlikely() annotations that match the GCC defaults
(and are thus pointless); add an "else" to highlight code flow.
This patch doesn't change driver behavior.
