[PATCH] xfs: Improve error handling in xfs_mru_cache_create()

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 10 Jun 2025 14:50:07 +0200

Simplify error handling in this function implementation.

* Delete unnecessary pointer checks and variable assignments.

* Omit a redundant function call.


This issue was detected by using the Coccinelle software.
