For some reason, the sme_global_mtx seems to already be locked when

No, it is not initialized:
That is more in line with my expectations. I was surprised that the
lock info from Wiz and bch both showed that the owner was curlwp.
The basic problem is that the device configuration is being done long
before the module subsystem is fully initialized. And we cannot simply
initialize the module subsystem earlier, as many of the modules are
devices or pseudodevices which require the configuration system to be
available! Chicken vs egg...
I've got a couple of ideas, but they'll take a few days to gestate, and
then a bit more time to discuss on tech-kern before implementing. As
much as I don't want to do it, I might have to revert that series of
commits. And due to a current illness, even the revert might take a
couple days.
