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.

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.
