host does not get updated to the resolved address if rdns is enabled

[nulman]

when using socksocket.getpeername() you get the peer url if rdns is set the True and an IP if rdns is set to False

I think the cause is at line 567. The if does not update host so later calls to getpeername return the url instead of the ip if rdns is True

This is with socks5, with socks4 It gets weirder and the address I get back is 0.0.0.1

也遇到类似问题，写一个socks.socksocket的子类，重新写一个_write_SOCKS5_address函数，不过是直接写死了host，期待更好解决方法
