builtin-remote: refactor duplicated cleanup code

This patch moves identical lines of code into a cleanup function. The
function has two callers and is about to gain a third.

Also removed a bogus NEEDSWORK comment per Daniel Barkalow:

  Actually, the comment is wrong; "remote" comes from remote_get(),
  which returns things from a cache in remote.c; there could be a
  remote_put() to let the code know that the caller is done with the
  object, but it wouldn't presently do anything.
