netfilter: fix ptr_ret.cocci warnings 

net/netfilter/nft_numgen.c:117:1-3: WARNING: PTR_ERR_OR_ZERO can be used
net/netfilter/nft_hash.c:180:1-3: WARNING: PTR_ERR_OR_ZERO can be used
net/netfilter/nft_hash.c:223:1-3: WARNING: PTR_ERR_OR_ZERO can be used

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