wiphy: Don't store rsne unless needed
...
Open networks do not contain a RSN element, so storing a 256 byte buffer
was too expensive.
This patch also has the side-effect of fixing detection of Open
Networks. Prior to this, if the scan results did not contain an RSN IE,
the 'rsne' variable would be set to all zeros. scan_get_ssid_security
would then be called, but instead of a NULL struct ie_rsn_info, a
non-null, but zerod out ie_rsn_info would be passed in. This caused the
code to work, but for the wrong reasons.
