nfsd: export NFSv4 callback op stats via netlink
Add a proc4cb-ops nested attribute to the server-stats netlink dump,
reusing the existing server-proc-entry (op/count) layout. The dump
gains a callback section that emits one entry per callback opcode
(OP_CB_GETATTR..OP_CB_OFFLOAD) from the per-netns callback counters,
paged across messages like the other per-operation sections.
This lets nfsstat report NFSv4 backchannel operation counts over
netlink, including CB_GETATTR which corresponds to the procfs
wdeleg_getattr line.
