md/raid5-cache: disable reshape completely We don't support reshape yet if an array supports log device. Previously we determine the fact by checking ->log. However, ->log could be NULL after a log device is removed, but the array is still marked to support log device. Don't allow reshape in this case too. User can disable log device support by setting 'consistency_policy' to 'resync' then do reshape.
