FILS: Use FILS auth alg when connecting using PMKSA caching

When a PMKSA cache entry is available and used for connection with FILS
key management suite, use FILS authentication algorithm for connection
even if ERP keys are not available. This scenario may happen when
applications using wpa_supplicant cache persistently only PMKSA but not
ERP keys and reconfigures wpa_supplicant with PMKSA cache after
restarting wpa_supplicant.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However, SME-in-driver cases, complete FILS authentication
without PMKSA caching is performed.

Fix SME-in-driver behavior by setting authentication algorithm to
WPA_AUTH_ALG_FILS when connecting to a FILS AP using PMKSA caching.
