mailbox: mtk-cmdq: Fix runtime PM leak in cmdq_mbox_flush()
pm_runtime_get_sync() leaves the runtime PM usage counter incremented
even when it fails, but cmdq_mbox_flush() returns the error without
dropping it. The same happens when the GCE thread does not drain in
time and the function bails out with -EFAULT.
Undo the reference on both error paths.
Fixes: b0524f7c9635 ("mailbox: mediatek: implement flush function")
