t3305: fix ignored exit code inside loop
When we test deleting notes, we run "git notes remove" in a loop. However, the exit value of the loop will only reflect the final note we process. We should break out of the loop with a failing exit code as soon as we see a problem. Note that we can call "exit 1" here without explicitly creating a subshell, because the while loop on the right-hand side of a pipe executes in its own implicit subshell. Note also that the "break" above does not suffer the same problem; it is meant to exit the loop early at a certain number of iterations. We can bump it into the conditional of the loop to make this more obvious.
