[PATCH 5.14 440/849] mailbox: Remove WARN_ON for async_cb.cb in cmdq_exec_done

From: jason-jh.lin <redacted>

[ Upstream commit ce1537fe288469bf68ee0aabdb860a790b4755ef ]

Because mtk_drm_crtc_update_config is not using cmdq_pkt_flush_async,
it won't have pkt->async_cb.cb anymore.

So remove the WARN_ON check of pkt->async_cb.cb at cmdq_exec_done.

Fixes: 1b6b0ce2240e ("mailbox: mtk-cmdq: Use mailbox rx_callback")
