usb-ehci: fix ehci_child_detach

Browse Source 
Looks like a cut+paste bug from ehci_detach.  When the device itself is
detached from a ehci port (ehci_detach op) we have to clear the
device pointer for the companion port too.  When a device gets removed
from a downstream port of a usb hub (ehci_child_detach op) the ehci port
where the usb hub is plugged in is not affected.
