Description: The current WPA supplicant implementation in Zephyr does not support multiple interfaces because it uses a single global control channel for interface communication. Since each interface (wpa_s instance) operates independently, this limitation prevents proper handling of multiple virtual interfaces (VIFs). This commit modifies WPA supplicant to support multiple interfaces by: * Removing the single global control channel. * Introducing a new ctrl_conn member in the wpa_s structure. * Assigning a separate ctrl_conn for each interface instance, enabling independent communication between WPA supplicant and Zephyr’s network layer. With this change, each virtual interface can now communicate with the control layer independently, allowing the coexistence of multiple VIFs. Signed-off-by: Hanan Arshad <[email protected]>

This change is part of a broader effort to enable multi-VIF support in the nRF7002 driver. A corresponding PR in the Zephyr repository will introduce driver-level changes to utilize this functionality.
