From: Jeff Layton <jlayton@xxxxxxxxxx>
Add a call to filemap_report_wb_err at the end of ext4_sync_file. This
will ensure that we check and advance the errseq_t in the file, which
allows us to track and report errors on all open fds when they occur.
Note that metadata writeback errors are not yet reported on all fds at
this point. That will be added in a later patch.
