Minor issue with hidden essid + wpa_supplicant + ndiswrapper

[Stian Skjelstad]

I'm a lucky owner of a usb wlan dongle with only a windows drivers, so
I'm forced to use ndiswrapper which works quite well.

After a lot of fiddeling I made it even to work on the WPA network here
in the building that has a hidden essid, but not straight forward.

ndiswrapper completely ignores the IW_SCAN_THIS_ESSID flag, which breaks
things a bit.

wpa_supplicant however is not very smart either, as it depends on the
wlan driver to support IW_SCAN_THIS_ESSID when used in surtain modes,
which again gives interesting boring results.

Please see bellow for sugestion of patches.
