asomers f384c045d8 OpenZFS 8473 - scrub does not detect errors on active spares 
Scrubbing is supposed to detect and repair all errors in the pool.
However, it wrongly ignores active spare devices. The problem can
easily be reproduced in OpenZFS at git rev 0ef125d with these
commands:

    truncate -s 64m /tmp/a /tmp/b /tmp/c
    sudo zpool create testpool mirror /tmp/a /tmp/b spare /tmp/c
    sudo zpool replace testpool /tmp/a /tmp/c
    /bin/dd if=/dev/zero bs=1024k count=63 oseek=1 conv=notrunc of=/tmp/c
    sync
    sudo zpool scrub testpool
    zpool status testpool # Will show 0 errors, which is wrong
    sudo zpool offline testpool /tmp/a
    sudo zpool scrub testpool
    zpool status testpool # Will show errors on /tmp/c,
                          # which should've already been fixed

FreeBSD head is partially affected: the first scrub will detect
some errors, but the second scrub will detect more.  This same
test was run on Linux before applying the fix and the FreeBSD
head behavior was observed.
