refs/reftable: fix leak when copying reflog fails

When copying a ref with the reftable backend we also copy the corresponding log records. When seeking the first log record that we're about to copy fails though we directly return from `write_copy_table()` without doing any cleanup, leaking several allocated data structures. Fix this by exiting via our common cleanup logic instead.
