Alexander Ivanov e3820d5f13 iotests: Fix test 131 after repair was added to parallels_open()
Images repairing in parallels_open() was added, thus parallels tests fail.
Access to an image leads to repairing the image. Further image check don't
detect any corruption. Remove reads after image creation in test 131.
