The MLO link-reconfiguration rework moved the per-phy num_sta
decrement inside a link_valid guard. link_valid is only set for
MLO links, but num_sta is incremented for every station link,
including the non-MLO deflink. Non-MLO stations bump num_sta
on association and never drop it on removal.
A non-zero num_sta forces connected-mode off-channel scanning which
prevents the directed probe exchange needed to find hidden APs.
Decrement phy->num_sta on the actual link teardown, pairing it with
the unconditional increment on link creation.
