So much for hubris!

sdio_release_host(wl->func);

And so on with write() (and dropping around wl12xx_init_ieee80211 to avoid
the recursive lock).  That kills some warnings.

iwconfig shows:

wlan0     IEEE 802.11bg  ESSID:""  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

So at least mac80211 is up and running.

I'm missing the NVS tables so 'ifconfig wlan0 up' bails on fw load.
