nfsd41: Backchannel: Setup sequence information
Follows the model used by the NFS client. Setup the RPC prepare and done
function pointers so that we can populate the sequence information if
minorversion == 1. rpc_run_task() is then invoked directly just like
existing NFS client operations do.
nfsd4_cb_prepare() determines if the sequence information needs to be setup.
If the slot is in use, it adds itself to the wait queue.
nfsd4_cb_done() wakes anyone sleeping on the callback channel wait queue
after our RPC reply has been received. It also sets the task message
result pointer to NULL to clearly indicate we're done using it.

[define and initialize cl_cb_seq_nr here]
[pulled out unused defintion of nfsd4_cb_done]
