Subject: [PATCH net-next v2 05/12] selftests/vsock: do not unconditionally
 die if qemu fails

From: Bobby Eshleman <bobbyeshleman@...a.com>

If QEMU fails to boot, then set the returncode (via timeout) instead of
unconditionally dying. This is in preparation for tests that expect QEMU
to fail to boot. In that case, we just want to know if the boot failed
or not so we can test the pass/fail criteria, and continue executing the
next test.
