279ed50441 wiphy: Don't parse attributes of scan reply 
The success or not of a scan command is found from the message directly.
There's no need to look for any attribute from the scan netlink answer.
The message is an error message or not, and that tells if the scan has
been started or not.

9c1780c0a1 wiphy: Use dbus object path as network key in hash 
Modifying a bit how networks are stored inside the hashtable:
1 - instead of the network id, the network's object path is used
2 - network holds the pointer of the object path
3 - the hashtable does not free the key (network_free() will)

This permits to optimize on:
1 - one memory allocation used for 2 distinct things
2 - remove the need to re-compute the object path (and the id) when it's
needed, it can use dircetly the one stored in the network structure.

e69b21ccdf 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.
