xfs: optimize log flushing in xfs_fsync
If we have a pinned inode it must have a log item attached to it.
Usually that log item will have ili_last_lsn already set, in which
case we only need to flush the log up to that LSN instead of doing a
full log force. This gives speedups of about 5% in some fsync heavy
workloads.
