Move the setting of the segtype upward, before testing free space.

So far, this patch has no effect, but it is needed for further patches
that create the individual virtual snapshots.

The reason is this: if shared store already exists, we create a virtual
snapshot. This is virtual segtype that allocates no space. If there is no
shared store, we must create the shared store on the top of linear segment
that allocates space. We need to move setting segtype before test for free
space (vg->free_count < lp->extents) because virtual segments shouldn't be
tested.
