Fix opRet value for volume info --xml call on non-existent volume

The opRet field was being assigned to 0 in the XML output when a
gluster volume info --xml call is made on a non-existent volume.
This change assigns a value of -1 to opRet for volume info calls
for non-existent volumes. Other fields like opErrno and opErrstr
are also assigned relevant values
