Shrink CAddress from 48 to 40 bytes on x64
`CAddress` inherits `CService` which is 28 bytes (on 64 bit machines).
`CAddress` then adds two member variables - one that requires 4 byte
alignment (`nTime`) and one that requires 8 byte alignment
(`nServices`).
Declare the smaller one first so that it fits in bytes 29..32.
On 32 bit machines this change has no effect and `CAddress` remains 40
bytes.
