In compression write endio sequence, the range which the compressed_bio writes is marked as uptodate if the last bio of the compressed (sub)bios is completed successfully. There could be previous bio which may have failed which is recorded in cb->errors. Set the writeback range as uptodate only if cb->errors is zero, as opposed to checking only the last bio's status. Backporting notes: in all versions up to 4.4 the last argument is always replaced by "!cb->errors".
