Rolf Neugebauer 58b500ccd9 kernel: Fix Null pointer de-reference in af_hvsock code ...

The Hyper-V socket patch has a bug which was triggered by a race condition when
the client connected and then immediately closed the connection before the
server would call accept(). This caused a kernel crash.

This patch was discussed with Dexuan Cui <decui@microsoft.com>, the original
author of the Hyper-V socket support.
