lock: Fix passing the wrong parameter when creating threads on Windows

Send the same parameters as the Unix implementation:
https://github.com/analogdevicesinc/libiio/blob/e54973a39f6f35fda3cf170d8585d48d65450e7b/lock.c#L131

This was causing random crashes when running iio_info on Windows. Error
was: "0xC0000005: Access violation executing location".
