We can use union for most of the temporary cruft (original ipv4/ipv6
address, source mac, physoutdev) since they're used during different
stages of br netfilter traversal.
Also get rid of the last two ->mask users.
Shrinks struct from 48 to 32 on 64bit arch.

br_nf_dev_queue_xmit must free skb in its error path.
NF_DROP is misleading -- its an okfn, not a netfilter hook.

br_nf_ip_fragment() is not needed when neither CONFIG_NF_DEFRAG_IPV4 nor
CONFIG_NF_DEFRAG_IPV6 is set.
struct brnf_frag_data must be available if either CONFIG_NF_DEFRAG_IPV4
or CONFIG_NF_DEFRAG_IPV6 is set.

Resolve compilation breakage when CONFIG_IPV6 is not set by moving the IPv6
code into a separated br_netfilter_ipv6.c file.
