Fix USB async events for composite devices

[arturmadrzak]

Refer to libmtp PR:
Async events (cancel and status) doesn't work for composite devices, when
MTP interface is not located as the first one in the descriptors. Control transfers,
by default are addressed to interface 0 but should be addressed to
actual interface. For this purpose wIndex field should contain
address of target interface.

The error line is located here:

android-file-transfer-linux/mtp/ptp/PipePacketer.cpp

Line 252 in 24089ee

0, 0, req.Data, timeout);

and code should look like:

_pipe->GetDevice()->WriteControl(
			(u8)(usb::RequestType::HostToDevice | usb::RequestType::Class | usb::RequestType::Interface),
			0x64,
			0, _interface_number_, req.Data, timeout);
