wifi: mac80211: don't select link ID if not provided in scan request
[ Upstream commit 80b0aacd1ad046b46d471cf8ed6203bbd777f988 ]
If scan request doesn't include a link ID to be used for TSF
reporting, don't select it as it might become inactive before
scan is actually started by the driver.
Instead, let the driver select one of the active links.
