objtool: Fix STACK_FRAME_NON_STANDARD for cold subfunctions
The recent STACK_FRAME_NON_STANDARD refactoring forgot about .cold
subfunctions. They must also be ignored.
Fixes the following warning:
drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_recv_msg.cold+0x0: unreachable instruction
Fixes: c84301d706c5 ("objtool: Ignore entire functions rather than instructions")
