ui: avoid 'local_err' variable shadowing in VNC SASL auth

The start_auth_sasl() method declares a 'Error *local_err' variable in
an inner if () {...} scope, which shadows a variable of the same name
declared at the start of the method. This is confusing for reviewers and
may trigger compiler warnings.
