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: e33bcba ("tee: add support for session's client UUID generation") [1] Signed-off-by: Sumit Garg <[email protected]> Signed-off-by: Jens Wiklander <[email protected]>
