Windows: Use STATUS_IO_TIMEOUT where STATUS_TIMEOUT was returned

STATUS_TIMEOUT causes the smb redirector to drop the connection.
STATUS_RETRY is interpreted by the smb redirector as if the error was
generated by the transport stack and not the smb server.
STATUS_IO_TIMEOUT is listed in the SNIA CIFS 1.0 spec as a valid
return code for the smb server.  Lets us that.
