Bug#431102: [PATCH]: (re)allow selection of zero length non-WPA ssid by wpa_supplicant_select_bss

[Kel Modderman]

Hi,

There is a regression since git commit 7d5d46c756afbb8ceb89107530dde43cc0f61a2d
Fri, 11 May 2007 03:52:46 +0000 (-0700), that prevents the simplest network
configuration from working:

network={
        key_mgmt=NONE
}

Attached patch to reinstate previous behaviour.
