After08fd5ccc3, the discard issuing code was organised such that if requesting an async discard or secure erase failed before the IO was issued (that is, calling __blkdev_issue_discard() returned an error), the failed zio would never be executed, resulting in txg_sync hanging forever waiting for IO to finish. This commit fixes that by immediately executing a failed zio on error. To handle the successful synchronous op case, we fake an async op by, when not using an asynchronous submission method, queuing the successful result zio as part of the discard handler. Since it was hard to understand the differences between discard and secure erase, and sync and async, across different kernel versions, I've commented and reorganised the code a bit to try and make everything more contained and linear.
