fs: adapt sync_file_range to new reporting infrastructure
Since it returns errors in a way similar to fsync, have it use the same
method for returning previously-reported writeback errors.
Signed-off-by: Jeff Layton <jlayton(a)redhat.com>
4241b859f3 fs: add a new fstype flag to indicate how writeback errors are tracked
