Unloading the mt7915e module with a MT7916 triggers multiples WARN in
__netif_napi_del_locked() and in page_pool_disable_direct_recycling()
because the driver does not disable the napi before destroying it.
This is troublesome since on MT7916 it is required to unload the module
and reinsert it with a different enable_6ghz parameter to change the
frequency. The system generally becomes unstable after reinserting the
module.
Fix it by disabling napi before deleting it. Also, do not delete napi
on WED queues since napi is neither used nor initialized on them.
