FILS: Fix PMK length for initial connection with FILS SHA384 AKM 

While the FILS authentication cases were already using the proper PMK
length (48 octets instead of the old hardcoded 32 octet), the initial
association case had not yet been updated to cover the new FILS SHA384
AKM and ended up using only a 32-octet PMK. Fix that to use 48-octet PMK
when using FILS SHA384 AKM.
