VectorCAN: Fix receiving frames with multiple open channels

As reason for the fix, see section "3.4.1 XLevent" in the Vector
documentation XL_Driver_Library_Manual_EN.pdf, which states:

  "portHandle: Internal use only".

This portHandle seems to be always zero and therefore channels
greater then zero could not receive frames.

Tested with Vectors simulated channels by sending frames to one
channel which in turn were received by both channels. The
sending channel had the local echo flag set, the other one not.

[ChangeLog][QCanBus][VectorCAN] Fixed a receive problem in the
VectorCAN plugin. When multiple channels were open, only the
first one could receive frames.
