Pass flags instead of flags_t type for USB2CAN

[jacobian91]

It looks like flags_t the type was being used instead of the flags argument.

This is the traceback when encountering this error:

Unable to create CAN node Traceback (most recent call last): File "...\site-packages\can\interfaces\usb2can\usb2canabstractionlayer.py", line 141, in open result = self.__m_dllBasic.CanalOpen(config_ascii, flags) │ │ └ <class 'ctypes.c_ulong'> │ └ b'F8BAFED8; 500' └ <can.interfaces.usb2can.usb2canabstractionlayer.Usb2CanAbstractionLayer object at 0x0000020F03E5D370> ctypes.ArgumentError: argument 2: <class 'TypeError'>: Don't know how to convert parameter 2

Since BusABC does not know these, we can also ignore them here.

Suggested change

	channel=channel, dll=dll, flags=flags, bitrate=bitrate, *args, **kwargs
	channel=channel, bitrate=bitrate, *args, **kwargs

[jacobian91]

I've also removed bitrate as it looks like BusABC doesn't use this either, so now this line is super().__init__(channel=channel, **kwargs).
I've removed the *args as well to prevent errors from positional vs keyword argument ordering. the BusABC argument can_filters could get passed into Usb2canBus via kwargs.

Thanks @jacobian91!

Optional style change, this documents that all additional positional arguments get ignored but won't throw an exception when passed in.

[felixdivo]

Yeah, that's fine. We don't have a unified handling of that case anyways.
