Subject: [PATCH 3/3] objtool, drm/vmwgfx: Don't ignore vmw_send_msg() for ORC

The following commit:

  0b0d81e3b733 ("objtool, drm/vmwgfx: Fix "duplicate frame pointer save" warning")

... marked vmw_send_msg() STACK_FRAME_NON_STANDARD because it uses RBP
in a non-standard way which violates frame pointer convention.

That issue only affects the frame pointer unwinder.  Remove the
annotation for ORC.
