Fields in struct rpcrdma_msg are __be32. Don't byte-swap these
fields when decoding RPC calls and then swap them back for the
reply. For the most part, they can be left alone.

svc_rdma_xdr_decode_deferred_req() indexes an array with an
un-byte-swapped value off the wire. Fortunately this function
isn't used anywhere, so simply remove it.

The byte_count argument is not used, and the function is called
only from one place.

My static checker marks everything from ntohl() as untrusted and it
complains we could have an underflow problem doing:
return (u32 *)&ary->wc_array[nchunks];
Also on 32 bit systems the upper bound check could overflow.

The svcrdma transport was un-marshalling requests in-place. This resulted
in sparse warnings due to __beXX data containing both NBO and HBO data.
The code has been restructured to do byte-swapping as the header is
parsed instead of when the header is validated immediately after receipt.
Also moved extern declarations for the workqueue and memory pools to the
private header file.

This logic parses the ONCRDMA protocol headers that
precede the actual RPC header. It is placed in a separate
file to keep all protocol aware code in a single place.
