wifi: iwlwifi: mld: trigger mlo scan only when not in EMLSR
When beacon loss happens or the RSSI drops, trigger MLO scan only
if not in EMLSR. The link switch was meant to be done when we are
not in EMLSR and we can try to switch to a better link.
If in EMLSR, we exit first and then trigger MLO scan.
