[wifi] Revert cyw43_wifi_link_status change for RP2040

Browse Source 
The switch from cyw43_tcpip_link_status to cyw43_wifi_link_status
was intended for 2026.3.0 alongside the arduino-pico 5.5.0 framework
update but was accidentally included in 2026.2.3.

With the old framework (3.9.4), cyw43_wifi_link_status never returns
CYW43_LINK_UP, so the CONNECTED state is unreachable. The device
connects to WiFi but the status stays at CONNECTING until timeout,
causing a connect/disconnect loop.
