r5cache: set MD_JOURNAL_CLEAN correctly
Currently, the code sets MD_JOURNAL_CLEAN when the array has
MD_FEATURE_JOURNAL and the recovery_cp is MaxSector. The array
will be MD_JOURNAL_CLEAN even if the journal device is missing.
With this patch, the MD_JOURNAL_CLEAN is only set when the journal
device presents.
