System Information
CentOS, Debian, Nvidia Titian, Nvidia GTX 780

Blender Version
Broken: 2.74 official

Short description of error
When you make a link from a sculpted object with higher multires subdiv level onto a non-sculpted object with lower multires subdiv level, the last object's polygons get blown away.

Exact steps for others to reproduce the error
Cube_01 has sculpting and third level of sculpt subdiv.
Cube_02 has no sculpting and second level of sculpt subdiv.
Cube_03 has the final phase of this bug.

You just make a link of modifiers from Cube_01 to Cube_02 or vice versa. I don't know which direction is right to describe.
The goal is to make Cube_02 having the same sculpt levels as Cube_01 has, despite of the sculpting occurred.
Anyways, the distortion of the mesh must not happen.

This is not implemented ('make link' for multires modifier), will actually lead to crash very easily (on debug build with asan e.g.).

Will see if we can fix this easily, otherwise will just prevent that type of modifier to be 'copied' here (like e.g. hook one).
