IEEE 802.11-2012 says: MSK has a lifetime that limits PMK_R0 and PMK_R1
lifetime. This is currently stored in r0_key_lifetime, but cache entries
are not actually removed.
This patch assumes a default MSK lifetime to be 3600s when
wpa_auth_derive_ptk_ft is called. This matches the default eapol_reauth
timeout and should probably be passed in from eapol state machine with some
future changes. For PSK, there is no such lifetime, but it also matters
less as FT-PSK can be achieved without inter-AP communication.
The expiration timeout is then passed from R0KH to R1KH. The R1KH verifies
that the given timeout for sanity, it may not exceed the locally configured
r1_max_key_lifetime.

FILS calls wpa_ft_store_pmk_r0 from wpa_auth.c. This is moved into a new
function wpa_ft_store_pmk_fils as VLAN, Identity, CUI need to be added as well.
The expires_in timeout needs to be reviewed.
