Fix T100578: Surface Deform modifier displays wrong in editmode 

This was the case when the "Show in Editmode" option was used and a
vertexgroup affected the areas.

Probably an oversight in {rBdeaff945d0b9}?, seems like deforming
modifiers always need to call `BKE_mesh_wrapper_ensure_mdata` in
`deformVertsEM` when a vertex group is used.
