Fix USB initialization.

Browse Source 
After USB RESET, all endpoints registers are being reset.  So,
there is no need to let each endpoint stall (it's disabled).
Actually, it's wrong to call usb_lld_stall_rx or usb_lld_stall_tx
before usb_lld_setup_endpoint, because other fields of endpoint
register are not specified after RESET.
