Basically the in-tree iwlmld module is loaded because that's not
installed along with other kernel modules in backport-iwlwifi-dkms.
iwlmld was introduced in commit a05e91d95449d3c7b71d73592902edd1a8f33487
("wifi: iwlwifi: mld: add the new operation mode"), core89 release, or
revision 12217, therefore affects Oracular and above.
Similar case happens on iwldvm module, which was introduced in commit
83063e236330631ec8b425ed1f19161001e25687 ("[NOUPSTREAM] prune: add DVM
to public"), core103, or revision 14346, therefore affects Resolute
only.
