From: Chuck Lever <chuck.lever@oracle.com>

Add a trace_nfs4_offload_status trace point that looks just like
trace_nfs4_offload_cancel. Promote that event to an event class to
avoid duplicating code.

An alternative approach would be to expand trace_nfs4_offload_status
to report more of the actual OFFLOAD_STATUS result.
