SCS: Renegotiate configured SCS policies with new AP after roaming
After STA roams to a new AP, previously configured SCS policies were not
automatically reapplied, as neither IEEE 802.11 nor WFA mandates policy
persistence across roaming events. However, it can be better for real
use cases to maintain the same configuration whenever possible.
Furthermore, the previously negotiated SCS session might still appear to
be active in wpa_supplicant status after roaming even when it was not
really in use anymore.
Ensures that active SCS rules are retriggered post-roaming to maintain
the agreed QoS levels, preserving consistent performance.
