spa_sync() currently grabs the write lock due to an old hack that is
documented by a comment:
We need the write lock here because, for aux vdevs,
calling vdev_config_dirty() modifies sav_config.
This is ugly and will become unnecessary when we
eliminate the aux vdev wart by integrating all vdevs
into the root vdev tree.
This has lead to deadlocks in rare edge cases from holding the write
lock. We can reduce incidence of these deadlocks by not grabbing the
write lock on pools without auxillary vdevs.
