Aha! The following diff to remove the call to rtl92c_dm_diginit() keeps 
me associated to the AP:

However, dhclient still takes a very long time get an IP address and the 
connection seems extremely lossy, much like it was when I could get a 
connection before. Perhaps there are two different bugs here, one for 
the association and one for the data loss?
