    xfs: Keep sb_bad_features2 consistent with sb_features2
    
    Currently when we modify sb_features2, we store the same value also in
    sb_bad_features2. However in most places we forget to mark field
    sb_bad_features2 for logging and thus it can happen that a change to it
    is lost. This results in an inconsistent sb_features2 and
    sb_bad_features2 fields e.g. after xfstests test xfs/187.
    
    Fix the problem by changing XFS_SB_FEATURES2 to actually mean both
    sb_features2 and sb_bad_features2 fields since this is always what we
    want to log. This isn't ideal because the fact that XFS_SB_FEATURES2
    means two fields could cause some problem in future however the code is
    hopefully less error prone that it is now.

    xfs: remove extra newlines from xfs messages
    
    xfs_warn() and friends add a newline by default, but some
    messages add another one.
    
    Particularly for the failing write message below, this can
    waste a lot of console real estate!

    xfs: initialize log buf I/O completion wq on log alloc
    
    Log buffer I/O completion passes through the high priority
    m_log_workqueue rather than the default metadata buffer workqueue. The
    log buffer wq is initialized at I/O submission time. The log buffers are
    reused once initialized, however, so this is not necessary.
    
    Initialize the log buffer I/O completion workqueue pointers once when
    the log is allocated and log buffers initialized rather than on every
    log buffer I/O submission.
