Fix a memory leak where "cat-file" will leak the "path" member. Seee5fba602e5(textconv: support for cat_file, 2010-06-15) for the code that introduced the offending get_oid_with_context() call (called get_sha1_with_context() at the time). As a result we can mark several tests as passing with SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true". As noted indc944b65f1(get_sha1_with_context: dynamically allocate oc->path, 2017-05-19) callers must free the "path" member. That same commit added the relevant free() to this function, but we weren't catching cases where we'd return early.
