[PATCH][next] drm/amdgpu: Fix missing assignment to variable r

[PATCH][next] drm/amdgpu: Fix missing assignment to variable r

[Colin Ian King]

Currently the call to function amdgpu_benchmark_move should be
assigning the return value to variable r as this is checked in
the next statement, however, this assignment is missing. Fix
this by adding in the missing assignment.

Addresses clang scan warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_benchmark.c:168:7: warning:
variable 'r' is uninitialized when used here [-Wuninitialized]

Fixes: 9645c9c9fb15 ("drm/amdgpu: plumb error handling though amdgpu_benchmark()")
