[PATCH 1/5] run-command.c: remove dead assignment in while-loop

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove code that's been unused since it was added in
c553c72eed6 (run-command: add an asynchronous parallel child
processor, 2015-12-15), the next use of "i" in this function is:

	for (i = 0; ...

So we'll always clobber the "i" that's set here. Presumably the "i"
assignment is an artifact of WIP code that made it into our tree.

A subsequent commit will need to adjust the type of the "i" variable
in the otherwise unrelated for-loop, which is why this is being
removed now.
