Fix MLO link reconfig 

Wi-Fi 7 R2 MRD describes Multi-Link Reconfiguration Add/Delete Links
without reassociation as an optional feature for station. Both add and
delete operations for different links can come in reconfiguration
multi-link element.

This feature enables dynamic link reconfiguration operations (add link
and/or delete link) on the multi-link setup of a STA MLD, either
triggered by the AP MLD or initiated by the STA MLD itself. This
avoids reassociation for any link reconfiguration operation.

Also update 'Multi-link reconfiguration – AP removal' documentation.
