svcrpc: don't error out on small tcp fragment
Though clients we care about mostly don't do this, it is possible for
rpc requests to be sent in multiple fragments. Here we have a sanity
check to ensure that the final received rpc isn't too small--except that
the number we're actually checking is the length of just the final
fragment, not of the whole rpc. So a perfectly legal rpc that's
unluckily fragmented could cause the server to close the connection
here.
