描述

### Describe the bug

No connection to a kvaser device with a simplest demo script (linux, latest kvaser driver CANlib 8.50,
4.5.0 - works perfectly.

### To Reproduce

OS: Xubuntu 22.04.5 LTS x86_64 Kernel: 5.15.0-100-generic
driver Kvaser Linux Drivers and SDK 5.51.461
CANlib 8.50 (file [libcanlib.so](https://libcanlib.so/).1.10.12)

- Simplest script and python-can 4.5.0

```import can
import can.interfaces.kvaser
try:
bus = can.interface.Bus( interface='kvaser', channel=0, bitrate=500000)
bus.shutdown()
except Exception :
print("Error")
```

works for me perfectly.

- update to a new version (4.6.1).
Error

or without try/except boundaries:

```Traceback (most recent call last):
File "/home/st/Documents/PyScripts/BLapp/tmp.py", line 4, in
bus = can.interface.Bus(interface='kvaser', channel=0, bitrate=500000)

return f(*args, **kwargs)
File "/home/st/Documents/PyScripts/BLapp/venv/lib/python3.10/site-packages/can/interface.py", line 137, in Bus
bus = cls(channel, **kwargs)
File "/home/st/Documents/PyScripts/BLapp/venv/lib/python3.10/site-packages/can/interfaces/kvaser/canlib.py", line 563, in __init__
canIoCtlInit(
File "/home/st/Documents/PyScripts/BLapp/venv/lib/python3.10/site-packages/can/interfaces/kvaser/canlib.py", line 102, in __check_status_operation
raise CANLIBOperationError(function, result, arguments)
can.interfaces.kvaser.canlib.CANLIBOperationError: Function canIoCtl failed - Error in parameter [Error Code -1]
```

### Expected behavior

I expected in to connect to the bus as 4.5.0 did.

### Additional context

OS and version: Xubuntu 22.04.5 LTS x86_64 Kernel: 5.15.0-100-generic
Python version: 3.10.12
python-can version: 4.6.1
python-can interface/s (if applicable): kvaser
