[PATCH 1/3] drm: property: One function call less in drm_property_create() after error detection

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 26 Dec 2023 08:44:37 +0100

The kfree() function was called in one case by the
drm_property_create() function during error handling
even if the passed data structure member contained a null pointer.
This issue was detected by using the Coccinelle software.

Thus use another label.
