Aha! mfi0 doesn't fully attach, yet it hangs around in the device tree
in a semi-attached state.  It probably has a bogus bus_space(9) tag &
handle, but mfi_detach() tries to use them, anyway -> crash.

BTW, there really are two mfi(4) adapters, right?  I've once seen a bug
where a device appeared to have an "alias" at a second PCI function.
