usb: ehci: do not invalidate a NULL buffer Its a valid use case to call ehci_submit_async() with a NULL buffer with length 0. E.g. from usb_set_configuration(). As invalidate_dcache_range() isn't able to judge if the address NULL is valid or not (depending on the SoC hardware configuration it might be valid) do the check in ehci_submit_async() as here we know that we don't have to invalidate such a buffer.
