From: Glen Lee <glen....@atmel.com>
Variable rxq_event, rxq_wait_event and rxq_wait have the same pointer.
nwi->os_context.rxq_wait_event = (void *)&g_linux_wlan->rxq_event;
g_wlan.rxq_wait = inp->os_context.rxq_wait_event;
They are never aquired(down) since down function was only called in
linux_wlan_rxq_task which was deleted in a previous patch.
So delete variable rxq_event, rxq_wait_event, rxq_wait and it's related codes.
