wifi: wilc1000: cancel the connect operation during interface down

Cancel the ongoing connection request to avoid any issue if the
interface is set down before the connection request is completed.
host_int_handle_disconnect was already available, so renamed it and used
the same API for 'ndio_close' cb.
