netfilter: nf_conntrack: padding breaks conntrack hash on ARM
commit 0794935e "[NETFILTER]: nf_conntrack: optimize hash_conntrack()" results in ARM platforms hashing uninitialised padding. This padding doesn't exist on other architectures. Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure everything is initialised. There were only 4 bytes that NF_CT_TUPLE_U_BLANK() wasn't clearing anyway (or 12 bytes on ARM).
