[PATCH] knfsd: nfsd4: add per-operation server stats 

Add an nfs4 operations count array to nfsd_stats structure.  The count is
incremented in nfsd4_proc_compound() where all the operations are handled
by the nfsv4 server.  This count of individual nfsv4 operations is also
entered into /proc filesystem.
