When there is a disk log, the new leg is added by stacking a new mirror on top of the old (one leg is the old mirror and the other leg is the newly added device). When the log is a 'core' log, the new leg is simply added to the existing mirror and all the devices are re-synced. The logic that handles collapsing the stacked 'disk' log mirror was having the effect of causing 'core' logged mirrors to begin resync'ing for a second time. I have used the 'CONVERTING' flag to indicate that a mirror is converting by way of stacking. This is no longer set for up-converting core logs. The final 'collapse' logic can safely be skipped for 'core' log mirrors - getting rid of the second resync.
