[PATCH] leds: trigger: oneshot: One function call less in pattern_init() after error detection

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 26 Dec 2023 22:02:08 +0100

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

Thus use another label.
