When running 2nd instance of WinHost.exe, below error is printed:
ERROR : Can not open Firmware Device File ../FV/FV_RECOVERY.fd...
The root cause is "RECOVERY.FD" is exclusively opened by the first
instance of WinHost.exe.
The patch changes to open "RECOVERY.FD" in shared way so that
2nd+ instance of WinHost.exe can still run successfully.
