usb: ehci, remove false clear-reset path
Some of the "EHCI ports reset forever" problems may be explained by
code paths which wrongly flagged resets as complete. This removes
two such paths; the ehci_hub_status_data() path should be the only one
to have an effect, since it was already properly flagged on the other
path. (Issue noted by Minhyoung Kim <a9a9@lge.com>.)
