## Summary

**CID 1642607: Unchecked Return Value.**

The function `rtems_can_queue_kern_initialize` in `cpukit/dev/can/can-quekern.c` calls `rtems_task_start` to launch the CAN queue garbage collector (`can_queue_dead_func`). Previously, the return value of this call was ignored.

**Issue:** If this task fails to start (e.g., due to resource exhaustion), the CAN driver would operate without its garbage collector. This leads to silent memory leaks and potential system instability when connections are closed, as resources are never freed.

**Fix:** Added a check for `RTEMS_SUCCESSFUL`. If the task fails to start, the initialization function now correctly returns `-1`, propagating the error and preventing the driver from entering an undefined state.
