eapol: Extract & keep track of desired ciphers
...
When our own WPA IE or RSN IE are set, extract group and pairwise
ciphers. These ciphers are the ones we desire to use for the secure
connection.

...
Step 4 is always sent without encrypted Key Data according to Section
11.6.6.5. In the case of WPA, Encrypted Key Data field is reserved, and
should always be 0. Thus it is safe to drop the !is_wpa condition.
