Currently there is an issue where metaslab_fastwrite_unmark() unmarks fastwrites on vdev_t's that have never had fastwrites marked on them. The 'fastwrite mark' is essentially a count of outstanding bytes that will be written to a vdev and is used in syncing context. The problem stems from the fact that the vdev_pending_fastwrite field is not being transferred over when replacing a top-level vdev. As a result, the metaslab is marked for fastwrite on the old vdev and unmarked on the new one, which brings the fastwrite count below zero. This fix simply assigns vdev_pending_fastwrite from the old vdev to the new one so this count is not lost.
