Daniel P. Berrange 7dfbfc7927 vnc: Don't demote authentication scheme when changing password/disabling login ...

Currently when disabling login in VNC, the password is cleared out and the
authentication protocol is forced to AUTH_VNC.  If you're using a stronger
authentication protocol, this has the effect of downgrading your security
protocol.

Fix this by only changing the authentication protocol if the current
authentication protocol is AUTH_NONE.  That ensures we're never downgrading.
