venus: fix memory leak

The fs getserverprefs command displays preference
ranks for file / volume location server machine
interfaces. In order to get the complete set of
preference ranks, the VIOC_GETSPREFS system call
might have to be called several times. If so, the
memory previously allocated should be released.
