bcache: avoid potential memleak of list of journal_replay(s) in the CACHE_SYNC branch of run_cache_set In the CACHE_SYNC branch of run_cache_set(), LIST_HEAD(journal) is used to collect journal_replay(s) and filled by bch_journal_read(). If all goes well, bch_journal_replay() will release the list of jounal_replay(s) at the end of the branch. If something goes wrong, code flow will jump to the label "err:" and leave the list unreleased. This patch will release the list of journal_replay(s) in the case of error detected. v1 -> v2: * Move the release code to the location after label 'err:' to simply the change.
