Stefan Haberland a90ad5c546 s390/dasd: fix performance drop ... commit 12d319b920fa673a4d5e7c1785c5dc82dcd15257 upstream. Commit ca369d51b ("sd: Fix device-imposed transfer length limits") introduced a new queue limit max_dev_sectors which limits the maximum sectors for requests. The default value leads to small dasd requests and therefor to a performance drop. Set the max_dev_sectors value to the same value as the max_hw_sectors to use the maximum available request size for DASD devices.
