[PATCH] ata: pata_octeon_cf: Use common error handling code in octeon_cf_probe()

[Markus Elfring <Markus.Elfring@web.de>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 17 Sep 2024 13:43:24 +0200

Add a label so that a bit of exception handling can be better reused
in a subsequent if branch of this function implementation.

This issue was detected by using the Coccinelle software.
