[ofw] [PATCH] winverbs/ep: handle receiving REQ then DREQ

[Sean Hefty]

For fast connections, it's possible to receive a DREQ immediately
after receiving a REQ, without an RTU coming in between.  If we've
sent a REP to the REQ, then the DREQ should be treated as if the
connection had been fully established.  (The RTU could be delayed,
and the communication established event is processed asynchronously,
so there's no way to tell for certain.)

This fixes an issue where the passive side Accept() call fails
waiting for the RTU, but receives a DREQ instead.
