sta: schedule sta_info timeout on creation

The codes looks to have a race-condition, where disconnected sta_infos
are created without scheduling a timeout.

As sta_infos are not connected by default, schedule the timeout upon
sta_info creation.

Fixes spurious spamming of "Refuse to add an already expired station
entry" on remote nodes.
