drm/amd/display: check top_pipe_to_program pointer
Clang static analysis reports this error
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:2870:7: warning:
Dereference of null pointer [clang-analyzer-core.NullDereference]
if
(top_pipe_to_program->stream_res.tg->funcs->lock_doublebuffer_enable) {
^
top_pipe_to_program being NULL is caught as an error
But then it is used to report the error.
So add a check before using it.
