net: openvswitch: don't call pad_packet if not necessary
The nla_put_u16/nla_put_u32 makes sure that
*attrlen is align. The call tree is that:
nla_put_u16/nla_put_u32
-> nla_put attrlen = sizeof(u16) or sizeof(u32)
-> __nla_put attrlen
-> __nla_reserve attrlen
-> skb_put(skb, nla_total_size(attrlen))
nla_total_size returns the total length of attribute
including padding.
