    Remove unnecessary log statement in LedgerDirsManager.getWritableLedgerDirs
    
    Descriptions of the changes in this PR:
    
    ### Motivation
    
    - when Bookie reaches diskusage threshold, LedgerDirsMonitor for every diskCheckInterval it logs NoWritableLedgerDirException call stack and message "All ledger directories are non writable".
    
    ### Changes
    
    So remove unneccessary log statement in LedgerDirsManager.getWritableLedgerDirs and let the caller deal with the thrown exception.
