[libvirt] [PATCH] Fix compiler warnings in virsh.c

[Laine Stump]

No functional change. These all generated compiler warnings which, for
some reason weren't converted to errors by
--enable-compiler-warnings=error.

* tools/virsh.c:
  * change return type frmo int to void on two functions that don't
    return a value.
  * remove unused variables/labels from two functions
  * eliminate non-literal format strings
  * typecast char* into xmlChar* when calling xmlParseBalancedChunkMemory
