51f1f6f517 drm/amdgpu: Fix static checker warning 
drivers/gpu/drm/amd/amdgpu/amdgpu_csa.c:49 amdgpu_allocate_static_csa()
error: uninitialized symbol 'ptr'.

the test if (!bo) doesn't work, as the bo is a pointer to a pointer.
if bo create failed, the *bo will be set to NULL.
so change to test *bo.
