wifi: cfg80211: Increase akm_suites array size in cfg80211_crypto_settings
Increase akm_suites array size in struct cfg80211_crypto_settings to 10
and advertise the capability to userspace. This allows userspace to send
more than two AKMs to driver in netlink commands such as
NL80211_CMD_CONNECT.
This capability is needed for implementing WPA3-Personal transition mode
correctly with any driver that handles roaming internally. Currently,
the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256,
SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing
the akm_suites array size to 10 should be reasonable for future
usecases.
