Konstantin Belousov 64b494a105 softdep_prelink(): only do sync if other thread changed the vnode metadata since previous prelink 
We call into softdep_prerename() and softdep_prelink() when there is
low free space in the journal. Functions sync all vnodes participating
in the VOP, in the hope that this would reduce journal utilization. But
if the vnodes are already synced, doing sync would only spend writes,
journal is filled not due to the records from modifications of our
vnodes.

Remember original seqc numbers for vnodes, and only initiate syncs when
seqc changed.
