dbus: Fix IEs getter to use wpa_bss_ie_ptr()

The wpa_bss structure's last element is an empty array. The forgotten
code here assumed that the array of IEs was contiguous to the wpa_bss
structure. This is not always the case anymore. Update this missed case
to use the new wpa_bss_ie_ptr() wrapper to send the correct array of IEs
over DBus.
