The retry loop checks the exact error. This code checks a boolean against
several apr_status_t values ;)

I think a helper function returning apr_status_t would be the best solution.

The helper should clear the svn_error_t and return only the status. Or it
should directly call apr to reset the attribute if that is an easier
solution. (The cost of allocating an error is not an issue as we are
delaying on the error anyway).
