Christoph Hellwig 7a36c8a98a xfs: avoid synchronous transaction in xfs_fs_write_inode 
We already rely on the fact that the sync code will cause a synchronous
log force later on (currently via xfs_fs_sync_fs -> xfs_quiesce_data ->
xfs_sync_data), so no need to do this here.  This allows us to avoid
a lot of synchronous log forces during sync, which pays of especially
with delayed logging enabled.   Some compilebench numbers that show
this:

In addition to that also remove the delwri inode flush that is unessecary
now that bulkstat is always coherent.
