Due to a flaw in 4589f3ae the number of unique combinations
could be calculated incorrectly. This could result in the
random combinations reconstruction being used when it would
have been possible to check all combinations.
This change fixes the unique combinations calculation and
simplifies the reconstruction logic by maintaining a per-
segment list of unique copies.
The vdev_indirect_splits_damage() function was introduced
to validate both the enumeration and random reconstruction
logic with ztest. It is implemented such it will never
make a known recoverable block unrecoverable.
