engine_lbgpu broken in debug build

[fweik]

The 3pt coupling part is broken. The offending commit is 74d2da9, so it was broken from the beginning. I'll deactivate the 3pt test for now.

Removed section from test:

         lbm = espressomd.lb.LBFluid_GPU(
             agrid=1.0,
             tau=S.time_step,
             fric=0.5,
             visc=1.0,
             dens=1.0,
             couple="3pt")
         self.run_and_check(S, lbm, tests_common.abspath("data/engine_lbgpu_3pt.vtk"))

What do we do about this?

[fweik]

Can you check if this still holds?

Update: 3pt coupling was completely rewritten in #2551, making this bug obsolete.

Re-introducing the engine 3pt coupling test is probably unnecessary since the existing 2pt coupling test covers the same code (lb_calc_particle_lattice_ia_gpu() is now a template for both 3pt and 2pt).
