tee: client UUID: Skip REE kernel login method as well
Since the addition of session's client UUID generation via commit [1],
login via REE kernel method was disallowed. So fix that via passing
nill UUID in case of TEE_IOCTL_LOGIN_REE_KERNEL method as well.
Fixes: e33bcbab16d1 ("tee: add support for session's client UUID generation") [1]
