A PSP hands out socket IDs from 1 again after sceNetAdhocTerm and
sceNetAdhocInit (net/adhoc/socketids, recorded on a PSP). We kept
counting up. Pangya: Fantasy Golf tears down the network between its
room and the round, and then keeps using socket 1 without looking at
what PdpCreate returned, so every send and receive failed with
INVALID_SOCKET_ID and each player saw the other as "Off-line".
