    John reported the following warning:
    
    net/wireless/nl80211.c: In function ‘nl80211_tx_mgmt’:
    net/wireless/nl80211.c:5286:8: warning: ‘hdr’ may be used uninitialized in this function
    
    Evidently, his version of gcc isn't able to see that
    when "msg" is initialized, "hdr" must also be. My
    gcc, 4.6.1, can actually see that and doesn't warn.
    Simply initialize the variable to NULL. That means
    if the compiler was ever right we'll crash though so
    isn't really optimal since it may hide warnings from
    the compiler when somebody modifies this code in the
    future.
