fix: swap dataset.rs warning argument order (#6683)

Prior to this commit, we emitted a warning that would log the index
structure in front of the error message that produced the warning. If
the index structure was so large that it caused the log processor to
truncate the log line, the original error message could be lost.

This changes the warning line to put the error ahead of the structure.
