USB: EHCI: remove dead code in the periodic scheduler

Browse Source 
This patch (as1409) removes some dead code from the ehci-hcd
scheduler.  Thanks to the previous patch in this series, stream->depth
is no longer used.  And stream->start and stream->rescheduled
apparently have not been used for quite a while, except in some
statistics-reporting code that never gets invoked.
