netdevsim: fix ptr_ret.cocci warnings

drivers/net/netdevsim/dev.c:937:1-3: 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: 6556ff32f1 ("netdevsim: use IS_ERR instead of IS_ERR_OR_NULL for debugfs")
