We loop over the refs to push, building up a strbuf with the set of
"push" directives to send to the remote helper. But if the atomic-push
flag is set and we hit a rejected ref, we'll bail from the function
early. We clean up most things, but forgot to release the strbuf.

Fixing this lets us mark t5541 as leak-free.

Arguably this whole function could benefit from a cleanup goto, but it's
a little non-trivial. So I stuck with simple-and-stupid.
