nfs: ensure correct writeback errors are returned on close() [ Upstream commit 67dd23f9e6fbaf163431912ef5599c5e0693476c ] nfs_wb_all() calls filemap_write_and_wait(), which uses filemap_check_errors() to determine the error to return. filemap_check_errors() only looks at the mapping->flags and will therefore only return either -ENOSPC or -EIO. To ensure that the correct error is returned on close(), nfs{,4}_file_flush() should call filemap_check_wb_err() which looks at the errseq value in mapping->wb_err without consuming it.
