Subject: [PATCH net-next v6 08/10] wifi: qtnfmac: Use netdev dummy allocator helper

There is a new dummy netdev allocator, use it instead of
alloc_netdev()/init_dummy_netdev combination.

Using alloc_netdev() with init_dummy_netdev might cause some memory
corruption at the driver removal side.

Fixes: 61cdb09ff760 ("wifi: qtnfmac: allocate dummy net_device dynamically")
