HS 2.0R2: Fix temporary network disabling in Deauth Req case

Commits 7ef6947993d4b09dea6797b96f34dbcfed57d90e and
533536d82ac63512c31ff0bae403d437392d34e0 added this temporarily
disabling case, but those commits were merged in without having been
converted to the new os_reltime design used for ssid->disabled_until.
Consequently, they ended up disabling the network for 44 years or so too
long time (depending on what values the relative timestamp had
accummulated so far). Fix this by using relative timestamps
consistently.
