[PATCH] drm/amdgpu: Remove ununsed variable that holds a return value

[Carlos Eduardo Gallo Filho]

Compiling amdgpu with W=1 get that unused-but-set-variable warning.

drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c: In function ‘amdgpu_mes_ctx_alloc_meta_data’:
drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c:1099:13: warning: variable ‘r’ set but not used [-Wunused-but-set-variable]
 1099 |         int r;
      |             ^

That variable is used to hold the return value of amdgpu_bo_create_kernel()
function call.

Remove r to fix the warning.
