USB: hub: Revert commit bd0e6c96 ("usb: hub: try old enumeration scheme first for high speed devices")

Commit bd0e6c96 ("usb: hub: try old enumeration scheme first for
high speed devices") changed the way the hub driver enumerates
high-speed devices.  Instead of using the "new" enumeration scheme
first and switching to the "old" scheme if that doesn't work, we start
with the "old" scheme.  In theory this is better because the "old"
scheme is slightly faster -- it involves resetting the device only
once instead of twice.

However, for a long time Windows used only the "new" scheme.  Zeng Tao
said that Windows 8 and later use the "old" scheme for high-speed
devices, but apparently there are some devices that don't like it.
William Bader reports that the Ricoh webcam built into his Sony Vaio
laptop not only doesn't enumerate under the "old" scheme, it gets hung
up so badly that it won't then enumerate under the "new" scheme!  Only
a cold reset will fix it.

Therefore we will revert the commit and go back to trying the "new"
scheme first for high-speed devices.
