[PATCH] iotests: Fix 051 output after qdev_init_nofail() removal

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Commit 96927c744 replaced qdev_init_nofail() call by
isa_realize_and_unref() which has a different error
message. Update the test output accordingly.

Gitlab CI error after merging b77b5b3dc7:
