fix(legacy-mcu1): backport Linux 7.3 cfg80211 support

Backport main commit 2c4ab4b421 to
legacy-mcu1, preserving the branch's MCU1 firmware and loader profile.
Adapt the probe status link ID, probe_peer callback and input cookie APIs;
retain cfg80211-assigned cookies through asynchronous completion paths.

Add an isolated native-kernel build check and record the regression results.
The original branch reproduces all six reported errors on 7.3-rc3. The fix
builds all three modules and passes MODPOST on upstream 7.3 final and Ubuntu
7.3-rc3, 7.2 and 6.17 headers. The final-release module_layout CRCs match
the fully built test kernel. Hardware operation has not been tested.
