esp8266/modnetwork: Fix wlan.scan() method so it returns all networks.

According to the Arduino ESP8266 implementation the first argument to the
wifi scan callback is actually a bss_info pointer.  This patch fixes the
iteration over this data so the first 2 entries are no longer skipped.

Fixes issue #2372.
