[nrf fromtree] modules: hostap: Update WPA supplicant to use per-VIF control channel

Update WPA supplicant functions to pass the control channel (socket) as a
parameter instead of relying on a global socket. This change aligns with
the PR 80 modifications in hostap repo and ensures that each Virtual
Interface (VIF) uses its dedicated control channel for communication.
