Using variables from the outer scope unnecessarily complicates the code and
leads to issues.
This patch fixes the bug when having an "adhoc" wifi-iface section before a
"sta" section prevents wpa_supplicant from using the key specified in the
corresponding section as it tries to use the "adhoc" key instead (1 by
default).
