[PATCHv2 RFC net-next] net/vxlan: Fix kernel unaligned access in __vxlan_find_mac

[Sowmini Varadhan <sowmini.varadhan@oracle.com>]

__vxlan_find_mac invokes ether_addr_equal on the eth_addr field,
which triggers unaligned access messages, so rearrange vxlan_fdb
to avoid this in the most non-intrusive way.

v2: Alexander Duyck comments: make eth_addr[] 64b aligned.
