Jouni Malinen 4ae3f39720 Add a helper function for recognizing BIP enum wpa_alg values
Use a shared wpa_alg_bip() function for this and fix the case in
nl_add_key() to cover all BIP algorithms. That fix does not change any
behavior since the function is not currently used with any BIP
algorithm, but it is better to avoid surprises should it ever be needed
with IGTK.
