[PATCH] net: fjes: Refactor a string comparison in is_extended_socket_device()

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 20 Sep 2024 13:56:44 +0200

Assign the return value from a strncmp() call to a local variable
so that an if statement can be omitted accordingly.

This issue was detected by using the Coccinelle software.
