MFC r339335: Avoid zero-sized kmem_alloc() in vdev_compact_children().

The device evacuation code adds a dependency that
vdev_compact_children() be able to properly empty the vdev_child
array by setting it to NULL and zeroing vdev_children.  Under Linux,
kmem_alloc() and related functions return a sentinel pointer rather
than NULL for zero-sized allocations.

This is a part of ZoL port of device removal patch:
