wifi: mac80211: properly skip link info driver update

Browse source 
If the interface isn't (yet) added to the driver, skip the
link info update. This was previously done for the BSS info
changes, but I forgot to copy the same check here.

Fixes: 7b7090b4c6 ("wifi: mac80211: split bss_info_changed method")
