Does the below fix the issue?

So far, so good! But, part of why it was so hard for me to bisect to the Subject: commit was 'cause it didn't always OOPS; but I'll continue to test on the most-likely failure mode (CalDigit TS4 to TB NVMe adaptor connected at suspend, then nothing (or USB-C dock) on resume).

But if this does indeed fix it, this will make TWO crash bugs on resume squashed in less than 12 hours- gotta love Open Source Software!
