[PATCH] wpa_supplicant: Use unique IDs for networks and credentials

[Naïm Favier]

The id and cred_id variables are reset to 0 every time the
wpa_config_read function is called, which is fine as long as it is only
called once. However, this is not the case when using both the -c and -I
options to specify two config files.

This is a problem because the GUI, since eadfeb0e93748eb396ae62012b92d21a7f533646,
relies on the network IDs being unique (and increasing), and might get
into an infinite loop otherwise.

This is solved by simply making the variables static.
