描述

### Describe the bug
When there is an invalid frame on CAN bus (in our case CAN FD), PCAN first reports result PCAN_ERROR_ILLDATA and then it send the error frame. If the PCAN_ERROR_ILLDATA is not ignored, python-can throws an exception.

### To Reproduce
A packet like the one in this screenshot has to be received.

### Expected behavior
python-can should ignore the PCAN_ERROR_ILLDATA because it carries no useful information. The error can be then detected by the error frame which PCAN generates right after.

### Additional context

OS and version: Windows 11
Python version: Python 3.12
python-can version: Latest commit in main - c7121310253c42c6410a70bc8b4f27a51b8b4411
python-can interface/s (if applicable): PCAN-USB FD (using pcan interface)
