wifi: mac80211: fix unassigned variable access

In ieee80211_latest_active_link_conn_timeout() we loop over all
sta->links in order to compute the timeout expiring last across
all links.

Such timeout is stored in `latest_timeout` which is used in the
time_after() comparison before having been initialized.

Fix this behaviour by initializing the variable to `jiffies` and
adapt surrouding conditions accordingly.

Note that the caller assumed latest_timeout to be 0 if no active
link was found. This is not appropriate because jiffies=0 is a
valid (and recurrent, although not often) point in time.
By using `jiffies` as default value for latest_timeout, we can
fix the caller as well.
