NFSD: Add an nfsd_cb_offload tracepoint

Record the arguments of CB_OFFLOAD callbacks so we can better
observe asynchronous copy-offload behavior. For example:

nfsd-995   [008]  7721.934222: nfsd_cb_offload:
        addr=192.168.2.51:0 client 6092a47c:35a43fc1 fh_hash=0x8739113a
        count=116528 status=0
