Matteo Croce 1478e902bc virt_wifi: fix error on connect 
[ Upstream commit 17109e9783 ]

When connecting without first doing a scan, the BSS list is empty
and __cfg80211_connect_result() generates this warning:

$ iw dev wlan0 connect -w VirtWifi

wlan0 (phy #0): connected to 00:00:00:00:00:00

Add the fake bss just before the connect so that cfg80211_get_bss()
finds the virtual network.
As some code was duplicated, move it in a common function.
