xfs: cleanup I/O-related buffer flags
Remove the unused and misnamed _XBF_RUN_QUEUES flag, rename XBF_LOG_BUFFER to the more fitting XBF_SYNCIO, and split XBF_ORDERED into XBF_FUA and XBF_FLUSH to allow more fine grained control over the bio flags. Also cleanup processing of the flags in _xfs_buf_ioapply to make more sense, and renumber the sparse flag number space to group flags by purpose.
