[PATCH] io_uring: Remove unneeded if check in io_free_batch_list()

From: Thorsten Blum
Date: Sun Aug 11 2024 - 18:29:10 EST


kfree() already checks if its argument is NULL. Remove the unneeded if
check and fix the following Coccinelle/coccicheck warning reported by
ifnullfree.cocci:

WARNING: NULL check before some freeing functions is not needed
