[PATCH 4.14 03/41] selftests/x86/entry_from_vm86: Exit with 1 if we fail

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Lutomirski <luto@xxxxxxxxxx>

commit 327d53d005ca47b10eae940616ed11c569f75a9b upstream.

Fix a logic error that caused the test to exit with 0 even if test
cases failed.
