[PATCH] reiserfs: do not add save links for O_DIRECT writes

We add a save link for O_DIRECT writes to protect the i_size against the
crashes before we actually finish the I/O.  If we hit an -ENOSPC in
aops->prepare_write(), we would do a truncate() to release the blocks which
might have got initialized.  Now the truncate would add another save link
for the same inode causing a reiserfs panic for having multiple save links
for the same inode.
