Patrick Steinhardt 6771e2012e builtin/submodule--helper: fix leaking buffer in is_tip_reachable ...

The `rev` buffer in `is_tip_reachable()` is being populated with the
output of git-rev-list(1) -- if either the command fails or the buffer
contains any data, then the input commit is not reachable.

The buffer isn't used for anything else, but neither do we free it,
causing a memory leak. Fix this.
