[libvirt] [DRAFT PATCHv5 9/9] rpc: removes the removal of unused variable i

[Hu Tao]

the removal of unused variable i also removes codes like
this:

if (!xdr_int (xdrs, &objp->remote_typed_param_value_u.i))

which should not be removed.

Sorry I'm not familiar with perl and can't find a perfect way
to deal with this.
