Jeff King 6636cf7e90 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.
