When iomuxing is used we must not only deregister the device with stdio.c, but also remove the reference to the device in the console_devices array used by console-muxing. Add a call to iomux_doenv to usb_kbd_deregister to update console_devices, which will drop the reference.
This fixes the console filling with "Failed to enqueue URB to controller" messages after a "usb stop force", or when the USB keyboard is gone after a "usb reset".
