  -----------
  MdeModulePkg ScsiDiskDxe: Fix hang issue when reconnecting an ISCSI device

The 'Reset' function for BlockIO(2) in ScsiDiskDxe should return
EFI_SUCCESS instead of EFI_DEVICE_ERROR when a device does not support
reset feature.

Otherwise, a 'reconnect -r' action when an ISCSI device is attached will
cause system hang.
