wifi: nl80211: force WLAN_AKM_SUITE_SAE in big endian in NL80211_CMD_EXTERNAL_AUTH
User-space supplicant (observed at least on wpa_supplicant) historically
parses the NL80211_ATTR_AKM_SUITES from the NL80211_CMD_EXTERNAL_AUTH
message as big endian _only_ when its value is WLAN_AKM_SUITE_SAE, while
processing anything else in host endian. This behavior makes any driver
relying on SAE external auth to switch AKM suite to big endian if it is
WLAN_AKM_SUITE_SAE. A fix bringing compatibility with both endianness
has been brought into wpa_supplicant, however we must keep compatibility
with older versions, while trying to reduce the occurences of this manual
conversion in wireless drivers.
Add the be32 conversion specifically on WLAN_AKM_SUITE_SAE in nl80211 layer
to keep compatibility with older wpa_supplicant versions.
