Until now, all the traffic was blocked during scan operation. However,
scan operation is going to be used to implement Remain On Channel (ROC).
In this case, special frames (marked with IEEE80211_TX_CTL_TX_OFFCHAN)
must be sent during the operation.
These frames need to be sent on the virtual interface #2. Until now,
this interface was only used by the device for internal purpose. But
since API 3.9, it can be used to send data during scan operation (we
hijack the scan process to implement ROC).
Thus, we need to change a bit the way we match the frames with the
interface.
Fortunately, the frames received during the scan are marked with the
correct interface number. So there is no change to do on this part.

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.

The wfx driver is now mature enough to leave the staging area.
