Subject: userfaultfd: selftest: explicit failure if the SIGBUS test failed

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andrea Arcangeli <aarcange@xxxxxxxxxx>
Subject: userfaultfd: selftest: explicit failure if the SIGBUS test failed
Showing zero in the output isn't very self explanatory as a successful
result. Show a more explicit error output if the test fails.
