firmware: usb: call USBD_HAL_DISCONNECT while usb init to recover from resets:

The firmware doesn't recover from a OSMO_ASSERT() which direct reset the board. After the reset the firmware will waits forever for the USBD state USBD_STATE_CONFIGURED. By adding the explicit USBD_HAL_DISCONNECT the board always recovers.
