SUNRPC: Fix rpc_task_force_reencode

commit 2574cc9f4ffc6c681c9177111357efe5b76f0e36 upstream.

This patch fixes the bug that was reported in
  http://bugzilla.kernel.org/show_bug.cgi?id=14053

If we're in the case where we need to force a reencode and then resend of
the RPC request, due to xprt_transmit failing with a networking error, then
we _must_ retransmit the entire request.
