Subject: [PATCH net-next v4 07/12] selftests/vsock: add check_result() for
 pass/fail counting

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

Add check_result() function to reuse logic for incrementing the
pass/fail counters. This function will get used by different callers as
we add different types of tests in future patches (namely, namespace and
non-namespace tests will be called at different places, and re-use this
function).

Changes in v4:
- fix botched rebase
- use more consistent ${VAR} style

Changes in v3:
- increment cnt_total directly (no intermediary var) (Stefano)
- pass arg to check_result() from caller, dont incidentally rely on
  global (Stefano)
- use new create_pidfile() introduce in v3 of earlier patch
- continue with more disciplined variable quoting style
