[libvirt] [PATCH 1/2] xenconfig: Properly check retval of virDomainGraphicsListenSetAddress

[Michal Privoznik]

The function, like others in our code, returns zero on success
and a negative value on error. However, there are two places in
xenconfig source code where we check for non-zero value. While
the function can't currently return a positive value, those
checks look okay, but does not really follow our style.
