Do not copy an SSID into the probe request template because hardware
will add the SSID by itself.
I have verified that probe requests transmitted by the device still
look good and contain the SSID configured by ifconfig.
Note that the in-tree driver does not send probe requests right now
because active scanning is disabled. There are known problems when
active scanning is enabled that I still need to get back to.
ok?
