rpcrdma_prepare_hdr_sges() sets num_sge to one, then rpcrdma_prepare_msg_sges() sets num_sge again to the count of SGEs it added, plus one for the header SGE just mapped in rpcrdma_prepare_hdr_sges(). Let's just add the number we mapped, instead of setting num_sge again. The behavior should be the same, but the code is slightly clearer and less likely to break due to unrelated changes. Similarly, simplify mapped SGE counting by just adding the running count of SGEs before returning.
