wfx: use container_of() to get vif
Currently, upon virtual interface creation, wfx_add_interface() stores a reference to the corresponding struct ieee80211_vif in private data, for later usage. This is not needed when using the container_of construct. This construct already has all the info it needs to retrieve the reference to the corresponding struct from the offset that is already available, inherent in container_of(), between its type and member inputs (struct ieee80211_vif and drv_priv, respectively). Remove vif (which was previously storing the reference to the struct ieee80211_vif) from the struct wfx_vif, define a function wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with the newly defined container_of construct.
