Subject: [PATCH] LU-15358 tests: fix check in sanityn test_80b

Shellcheck found checks in sanityn test_80b using bad logic:

        [ $rc -ne 0 -o $rc -ne 16 ] || {
                echo "touch file failed with $rc1"
                break;
        }

This can never be false, so the subtest will never detect errors.
Fix these checks, along with some related style issues.

Test-Parameters: trivial testlist=sanityn mdscount=2 mdtcount=4 env=ONLY=80,ONLY_REPEAT=50
Fixes: 220e6cbfa65c5 ("LU-6475 mdt: race between open and migrate")
