Paul Dagnelie 7e945a5b3f Fix other nonrot bugs
There are still a variety of bugs involving the vdev_nonrot property
that will cause problems if you try to run the test suite with
segment-based weighting disabled, and with other things in the weighting
code. Parents' nonrot property need to be updated when children are
added. When vdevs are expanded and more metaslabs are added, the weights
have to be recalculated (since the number of metaslabs is an input to
the lba bias function). When opening, faulted or unopenable children
should not be considered for whether a vdev is nonrot or not (since the
nonrot property is determined during a successful open, this can cause
false negatives). And draid spares need to have the nonrot property set
correctly.
