wifi: iwlwifi: mvm: avoid always prefering single-link
The new link selection algorithm uses defaults values for BSS load if
the BSS Load element was not published by the AP.
For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR
grade to always be equal to the grade of the best link,
and then the best link grade is getting a bonus of 10 percent, meaning
that we will never activate EMLSR.
Change the logic to not give a bonus for the best link.
