live: fix ogChangeRepo invocation

Add missing samba credentials parameter in ogChangeRepo invocation.

Credentials are loaded from ogClient config file.

Any production deployment should use its own samba user and password.
ogChangeRepo fails when using default samba credentials in a production
environment.

Fixes: 3703fd6063 ("live: support native unicast cache image restore")
