[win-pv-devel] [PATCH] Fix ASSERTion failure in EVTCHN Close

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

The EVTCHN Channel structure contains a BOOLEAN Mask field that specifies
whether the Channel is aut0-masked on event upcall. The Close method was
failing to zero then and then falling over a later assertion that the
Channel structure had been zeroed out.
