The change is simple -- restore the original code so that the VDEV
path is updated when using by-id paths. The more challenging part
was to devise a second ZTS test, that would test auto-replace for
'by-id' and help prevent a future regression.
With that new test, we can now do an A|B test with , and without,
the fix to confirm that auto-replace for by-id paths works. The
existing auto-replace test, functional/fault/auto_replace_001_pos,
will confirm that we didn't break auto-replace for 'by-vdev' paths.
In the original functional/fault/auto_replace_001_pos test, the disk
wipe (using dd) was not effective in removing the partitioning since
the kernel was never informed of the wipe.
Added a call to wipefs(8) so that the kernel is informed and ZED will
re-partition the device.
Added a validation step that the re-partitioning occurred by
confirming that the GPT partition UUID changes.
