[PATCH] rpc_pipefs: Replace one label in bl_resolve_deviceid()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 29 Dec 2023 13:18:56 +0100

The kfree() function was called in one case by
the bl_resolve_deviceid() 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 an other label.
