If job involved in dependency completes and is purged the logic
used to test for circular dependencies can use the invalid pointer
and generate an invalid memory reference before the pointer is

Without this change, the testing only happens with task/affinity

This bug was introduced in 2.5.2 for the case where a GPU count was
configured, but without device files. Unfortunately it left the
CUDA_VISIBLE_DEVICES environment variable unset if GPUs were configured,
but the job did not request any of them.
