[win-pv-devel] [PATCH 4/4] Abort any partially completed SRBs

[<owen.smith@xxxxxxxxxx>]

From: Owen Smith <owen.smith@xxxxxxxxxx>

When disabling, a SRB may be comprised of requests that have been
prepared and completed. Set the SrbStatus as early as possible, so
that any partially completed SRB is always failed.
