rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC
request or an RPC reply. In the case of a request, several
calculations and tests involving pos are unnecessary. In the case of a
reply, several calculations and tests involving pos are incorrect (the
code tests pos against the reply xdr buf's len field, which is always
0 at the time rpcrdma_convert_iovs is executed). This change removes
the incorrect/unnecessary calculations and tests involving pos.
This fixes an observed problem when reading certain file sizes over
NFS/RDMA.

Support for binary sysctls is being deprecated in 2.6.24. Since there
are no applications using the NFS/RDMA client's binary sysctls, it
makes sense to remove them. The patch below does this while leaving
the /proc/sys interface unchanged.
Please consider this for 2.6.24.
