drm/bridge: analogix_dp: Fix clk-disable removal

Commit 6579a03e68ff ("drm/bridge: analogix_dp: Remove the unnecessary
calls to clk_disable_unprepare() during probing") removed the mismatched
clock_disable calls from analogix_dp_probe.

But that patch was created and sent before
commit e5e9fa9f7aad ("drm/bridge: analogix_dp: Add support to get panel
from the DP AUX bus") was merged, so couldn't know about this change.

So in the original patch the last change is
    if (ret) {
	dev_err(&pdev->dev, "failed to request irq\n");
-		goto err_disable_clk;
+		return ERR_PTR(ret);
    }
    disable_irq(dp->irq);

    return dp;
-
-err_disable_clk:
-	clk_disable_unprepare(dp->clock);
-	return ERR_PTR(ret);
 }
 EXPORT_SYMBOL_GPL(analogix_dp_probe);

the analogix_dp_core.c actually now has the runtime-pm handling between
disable_irq() and return do introducing another goto err_clk_disable there.

So remove that one too and return an error pointer, to not create build
breakage.
