[PATCH 3/5] branch_get: return early on error

[Jeff King <peff@peff.net>]

Right now we simply check if "ret" is valid before doing
further processing. As we add more processing, this will
become more and more cumbersome. Instead, let's just check
whether "ret" is invalid and return early with the error.
