modules: nrf_wifi: Fix net API use

In d45cd67 the mayority of the
Zephyr codebased was changed to use the Zephyr native net_ prefixed
types, but some were forgotten.
Without this fix/change the code still builds as we are by now setting
CONFIG_NET_NAMESPACE_COMPAT_MODE. But when this is not set, things
fail to build.
