ZTS: Fix zpool_status_008_pos false positive

When checking that healthy vdevs[1-3] aren't shown omit the -s flag
so slow vdevs are not considered as described by the comment.  This
avoids the possibility of a false positive in the CI when ZIO_SLOW_IO_MS
is reduce to 160ms.  Additionally, clear the fault injection as soon
as it is no longer required for the test case.
