mm/zswap: fix error pointer free in zswap_cpu_comp_prepare()
commit 590b13669b813d55844fecd9142c56abd567914d upstream.
crypto_alloc_acomp_node() may return ERR_PTR(), but the fail path checks
only for NULL and can pass an error pointer to crypto_free_acomp(). Use
IS_ERR_OR_NULL() to only free valid acomp instances.
