Al Viro bd2843fe1f fix ufs write vs readpage race when writing into a hole ...

Followup to the UFS series - with the way we clear the new blocks (via
buffer cache, possibly on more than a page worth of file) we really
should not insert a reference to new block into inode block tree until
after we'd cleared it.
