[PATCH] nvmem: meson-efuse: fix ptr_ret.cocci warnings

[kbuild test robot <lkp-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

From: Fengguang Wu <fengguang.wu-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

drivers/nvmem/meson-efuse.c:64:1-3: WARNING: PTR_ERR_OR_ZERO can be used


 Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR

Generated by: scripts/coccinelle/api/ptr_ret.cocci

Fixes: 0d4f662ed6ff ("nvmem: meson-efuse: Do no gate COMPILE_TEST with MESON_SM")
