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

[Thorsten Blum <thorsten.blum@toblux.com>]

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
