smb3: add dynamic tracepoint for reflink errors

There are cases where debugging clone_range ("smb2_duplicate_extents"
function) and in the future copy_range ("smb2_copychunk_range") can
be helpful. Add dynamic trace points for any errors in clone, and
a followon patch will add them for copychunk.

  "trace-cmd record -e smb3_clone_err"
