wifi: cfg80211: only verify part of Extended MLD Capabilities

We verify that the Extended MLD Capabilities are matching between links.
However, some bits are reserved and in particular the Recommended Max
Links subfield may not necessarily match. So only verify the known
subfields that can reliably be expected to be the same. More information
can be found in Table 9-417o, in IEEE P802.11be/D7.0.
