free ref string returned by dwim_ref
A call to "dwim_ref(name, len, flags, &ref)" will allocate a new string in "ref" to return the exact ref we found. We do not consistently free it in all code paths, leading to small leaks. The worst is in get_sha1_basic, which may be called many times (e.g., by "cat-file --batch"), though it is relatively unlikely, as it only triggers on a bogus reflog specification.
