[adhoc] Fix The Warriors

[anr2me]

Apparently there are games (ie. The Warriors) who tried to do PtpSend immediately after PtpOpen, without trying to do PtpConnect first.

Do we have an issue about this, to tag for closing?

Looks okay, although it seems very odd to call send without connect.

[anr2me]

There are no issue opened related to networking on The Warriors.

Yeah it's an odd way to connect, i still need to test the behavior of PtpOpen to see whether it's possible to send without connecting first.
Currently this commit is the only way to make The Warriors to work properly, and shouldn't cause regression on other games.

After testing it on a small homebrew, looks like the error code returned from PtpSend was wrong, it should be "disconnected" instead of "not connected", and looks like PtpSend can get a success after PtpOpen (the other side was able to PtpAccept after PtpListen)

[anr2me]

Okay i'm done.

So basically,
If remote player is not Listening yet, the socket created by PtpOpen won't be connected, thus PtpSend will fail with error "disconnected" and the game need to do PtpConnect, or close the socket and PtpOpen again.
If remote player is already Listening, the socket created by PtpOpen will be connected, thus PtpSend can be successful.

Oh, that's making more sense indeed.
