Fix comparison to use correct symbol name (__rand vs. rand)

rand would be the address of rand() function and never NULL. The previous
version could have crashed on invalid AKA-AUTS command. Though, these
commands are only from hostapd which sends valid requests and as such,
the actual issue did not show up.
