autoscan: Fix potential freeing of uninitialized pointer
Commit 7c865c68536825d91e64e1545a1f6ed51526ebff introduced a code
path that can skip extra_ie initialization in wpa_supplicant_scan().
This could result in semi-random crashes when using the autoscan
mechanism. Fix this by initializing extra_ie to NULL.
