I did not find a mailing-list thread for "9828ed3f695a module: error out early
on concurrent load of the same module file", so replying here. This
commit breaks the basic CXL smoke test of loading the combination of
cxl_acpi, cxl_pci, and cxl_mem modules.

Just wanted to highlight this a test case for the next attempt at this
fix.
