wifi: iwlwifi: pcie: allocate dummy net_device dynamically
struct net_device shouldn't be embedded into any structure, instead, the owner should use the priv space to embed their state into net_device. Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct iwl_trans_pcie by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at iwl_trans_pcie_alloc. The private data of net_device becomes a pointer for the struct iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent given the net_device object.
