Multiple DVA Scrubbing Fix
Currently, there is an issue in the sequential scrub code which prevents self healing from working in some cases. The scrub code will split up all DVA copies of a bp and issue each of them separately. The problem is that, since each of the DVAs is no longer associated with the others, the self healing code doesn't have the opportunity to repair problems that show up in one of the DVAs with the data from the others. This patch fixes this issue by ensuring that all IOs issued by the sequential scrub code include all DVAs. Initially, only the first DVA of each is attempted. If an issue arises, the IO is retried with all available copies, giving the self healing code a chance to correct the issue. To test this change, this patch also adds the ability for zinject to specify individual DVAs to inject read errors into. We then add a new test case that utilizes this functionality to ensure scrubs and self-healing reads can handle and transparently fix issues with individual copies of blocks.
