rpc: clean up dregs from June 2010
rpc: clean up dregs from June 2010

In June 2010 I accidentally checked in pending
changes to package rpc in a compiler CL:
http://codereview.appspot.com/1736041

I backed them out by hand in a followup CL:
http://codereview.appspot.com/1736042

That followup CL missed the lines being deleted
in this CL, spotted by Petar.

hg diff -r 5678:5683 src/cmd/prof/gopprof \
        src/pkg/image/png/reader.go \
        src/pkg/rpc/client.go \
        src/pkg/rpc/jsonrpc/all_test.go \
        src/pkg/rpc/jsonrpc/server.go \
        src/pkg/rpc/server.go \
        test/arm-pass.txt

confirms that these lines in server.go are the
only ones that were missed by the original followup.

Fixes issue 1583.
