vfs: Fix vmtruncate() regression
If __block_prepare_write() was failed in block_write_begin(), the
allocated blocks can be outside of ->i_size.
But new truncate_pagecache() in vmtuncate() does nothing if new < old.
It means the above usage is not working anymore.
So, this patch fixes it by removing "new < old" check. It would need
more cleanup/change. But, now -rc and truncate working is in progress,
so, this tried to fix it minimum change.
