[win-pv-devel] [PATCH 4/9] Dont close ring during FrontendReset

[Owen Smith <owen.smith@xxxxxxxxxx>]

Closing the ring (and destroying the shared pages, etc) is not required
when a HwStorResetBus or SRB_FUNCTION_RESET_DEVICE is triggered.
Disabling the ring will cause any outstanding blkif_requests and SRBs to
be failed.
