So I ran into the problem as well, what I found was that the whole wiphy 
had to be moved over into the namespace manually with the iw command. 
After which you have to use the iw command again inside the container to 
create a new interface.  A word of caution,  I have found even though 
the phy is in another namespace you can still add vifs to it. Even 
though it is possible, don't! It will hang your system when you shutdown 
the container(s).

Hope this helps.
